Example input: (CNN) -- The goals just keep flowing for Lionel Messi, who on Sunday surpassed soccer legend Pele's mark of 75 in a calendar year to help Barcelona bounce back from a rare defeat. The Argentina star netted twice in the 4-2 win at Mallorca that kept the Catalans three points clear in Spain's La Liga, leaving him just nine short of Gerd Muller's all-time record. The 25-year-old, who became a first-time father earlier this month, was able to put a bit more enthusiasm into his new thumb-sucking celebration than when he scored late in the shock midweek Champions League loss to Scottish side Celtic. 'Leo continually breaks records. His goal tally is spectacular,' said Barca manager Tito Vilanova, who has yet to experience a domestic league defeat after his first 11 matches in charge, equaling the best start to a season set by Real Madrid. 'It takes other great players seven or eight seasons to score the amount of goals he scores in one season. Also, some of his goals are absolute beauties.'Read blog: Is loyalty Barca's biggest strength? Messi has now scored 64 goals for his club and 12 for his country this year, from just 59 matches overall. Pele managed 75 from 53 as a 17-year-old in 1958, helping Brazil to win the World Cup for the first of a record five times. Muller, a World Cup winner in 1974, surpassed Pele's record in a year that West Germany won the European Championship. Messi has yet to win a senior title with Argentina, though he won Olympic gold with the under-23 side in 2008. He has nine matches left this year to catch Muller -- six in La Liga, two in the Champions League and one in the Spanish Cup. His two goals against Malaga gave him 15 in the league this season, three clear of his big rival Cristiano Ronaldo -- who scored the opener in Real Madrid's 2-1 win on a waterlogged pitch at Levante in Sunday's late match. Ronaldo, switched to a central attacking role with Karim Benzema and Gonzalo Higuain out injured, suffered an early blow above the eye and was taken off at halftime. The Portugal captain is now Real's seventh highest league scorer with 124 goals since his arrival from Manchester United in 2009 in a world-record $130 million transfer. Levante leveled in the second half through Angel Rodriguez, but 20-year-old Alvaro Morata headed an 84th-minute winner with his first touch of the ball on his debut to keep Jose Mourinho's third-placed defending champions eight points behind Barcelona. Real inflicted Levante's first home defeat this season, hitting the crossbar twice and missing a penalty by Xabi Alonso, whose late freekick set up substitute Morata's winner. Atletico Madrid retained second place after beating Getafe 2-0. Adrian Lopez scored a first-half opener after his initial attempt was saved, while Arda Turan's second-half effort was allowed to stand despite a clear handball in the buildup. In Italy, Inter Milan failed to reduce Juventus' four-point lead after suffering a surprise 3-2 defeat at Atalanta. Veteran striker German Denis netted in the 60th and 67th minutes to put the home side 3-1 ahead, while Inter reduced the deficit through his fellow Argentine Rodrigo Palacio before Atalanta substitute Facundo Parra was sent off in time added on. Napoli stayed third with a 4-2 win at Genoa, while fourth-placed Fiorentina won 3-1 away to troubled 2010-11 Serie A champions AC Milan. Milan's sixth defeat in 12 league games left last season's runners-up in 13th place, with coach Massimiliano Allegri's future increasingly in doubt. Lazio consolidated fifth place with a 3-2 win in the capital derby against Roma, as both teams had a player sent off. In Germany, Bayer Leverkusen missed the chance to go above fourth-placed champions Borussia Dortmund after losing 3-1 to third-bottom Wolfsburg. Leverkusen stayed a point above Hanover, who won 4-2 at Stuttgart.

Q: (CNN) -- One of the three guns Adam Lanza used to kill 20 children and six adults at an elementary school in Newtown, Connecticut, was a military-style semiautomatic rifle known as an AR-15. That surprised and shocked a lot of people unfamiliar with America's gun culture. They questioned why such weapons are available and why anyone would need them. "Personally I don't know how any ordinary citizen can justify owning an automatic or semiautomatic gun," writes CNN commenter Mark Smerkanich. "Can't we leave those guns to the trained military?" Self-described gun owner Julie Jones-Hawkins comments, "I ... fully support a ban on rapid-fire weapons. Any weapon that can take out an entire kindergarten class is a problem." Here are five reasons many gun owners say they want military style rifles: . 'Some people play golf, others bowl. I shoot' "Every month or so I take my guns out to the range and shoot. It's thrilling, exciting and a great way to vent," says Christopher L. Kirkman, a Florida-based military-style gun owner. Kirman was one of more than 100 gun enthusiasts who shared opinions on CNN iReport about owning firearms that would have been banned under the now-expired 1994 federal weapons ban. "Sure, I could try to say that the reason I own these guns is self-defense, but the truth of the matter is that, although they will technically serve this purpose, they are not why I own them," he says. Michigan gun owner Ethan Daniels describes his enthusiasm for his rifle more succinctly, saying, "I like to shoot, and that is one heck of a fun carbine to plink with." iReport: Tell us why you own your military-style weapon . Background can factor into a gun owner's choice of weapon. "The AR-15 is what I am used to from my extensive training as an airborne infantryman," writes Nathan Lee. "Because of my training, it's what I feel the most comfortable with." Another reason for these guns is hunting. The AR-15 is a "good hunting platform. I've hunted coyote with it," says CNN iReporter MVR155, who owns two of the weapons. He asked to remain anonymous. Owners of military-style rifles also use them to hunt deer and other game. But some states have banned the AR-15 and its .223 caliber for deer hunting. Related: Newtown shooter's guns: What we know . 'It's cool' It may not be the best or most important reason, but military-style weapons often appeal to the enthusiast side of the American gun owner. Just like many car lovers who dream of owning a Lamborghini, many gun owners get excited about the idea of owning an AR-15. "There are people who buy certain types of firearms because they have a certain image -- the AR-15 is one of them," says Austin Nikel, a former AR-15 owner in Boulder, Colorado. "One thing about this country is how Hollywood has glorified the image behind those certain types of weapons. A lot of guys grow up with GI Joe, and that image is extremely attractive. It grabs you and affects you. "A lot of people buy the AR-15 because, well, it's cool." Apparently it wasn't cool enough for Nikel to hold on to. He ended up selling his AR-15 to his father. iReport: Why some own military-style weapons . 'A part of history' "Since coming of age -- and in the decades since -- I have collected many different firearms, some of them historical pieces, some for sport, some of them even the so-called 'assault weapons' that are now a controversy," says iReporter Hrothgar01. "Guns like these are as much a part of the history of this country as the muskets carried by pioneers, the rifles toted by doughboys in the trenches, and the other arms that have served and protected throughout the years. To hold one in your hands, appreciate its history and design, and to be able to take that piece of history to the range and work -- it is a feeling that many people in this debate do not understand or appreciate." Related story: By the numbers: Guns in America . 'Protecting my family' "I believe the foremost person responsible for protecting my family and myself is me," writes iReporter ShortyDoowap, who owns a pair of AR-15s. "These rifles provide me with the tools to perform that duty. I don't own these guns to target shoot, though I do that with them. I don't hunt with them, though I could in a pinch." Parks says he "would not hesitate to use one to simply defend my home and family from a single intruder if it became necessary." Related: Parents defend right to keep guns in the home . In some home-protection situations, fans say military-style rifles are generally more accurate than handguns. Rifles are generally easier to learn how to shoot, say military-style rifle owners. Like most firearms, military-style weapons such as the AR-15 are semiautomatic -- increasing protection because the shooter can fire off many shots without having to manually chamber a new bullet. With a bolt-action rifle or pump-action shotgun, firing multiple shots takes more time. "When you weigh it all out, these types of guns are stigmatized," says iReporter MVR155. Military-style weapons look more dangerous than other guns, he says, but really, there are many weapons available which are just as lethal, but which are not designed in a military style. iReport: One gun owner's solution . 'Fascination with the Second Amendment' "I am a proud owner of an AK-47," writes iReporter INGunOwner. "It's a terrific gun. Lots of fun to shoot. I own an AK because of my fascination with the Second Amendment, which I view as a backstop protector of freedom. Many people would argue that we have no use for it today because the government is trustworthy. "However since it acts as a deterrent, we can never measure exactly how much it has been effective. Perhaps the notion that people feel safe with our government after over 200 years is a testament to the Second Amendment value in balancing power with the citizens."
