<text>  Few people expect Manchester City to go to Barcelona and overturn a 2-1 deficit from the first leg and reach the quarter-finals of the Champions League. But heres 10 good reasons Manuel Pellegrinis men should travel in hope... 1 - CHELSEA PROVED MIRACLES CAN HAPPEN . Chelsea were 2-1 down on aggregate to Barcelona and down to only 10 men in their second leg at the Nou Camp in 2012 and still went through. Goals from Sergio Busquets and Andres Iniesta put Barca in control even before John Terry was sent off. Then, incredibly, Ramires scored on the stroke of half-time and after surviving immense pressure, Fernando Torres scored to book Chelseas place in the final, which they went on to win. Chelsea sealed a place in the 2012 Champions League final by drawing 2-2 with Barcelona at the Nou Camp . 2 - PELLEGRINI CAN TAP INTO MALAGA . Barcelona lost their last game at the Nou Camp on February 21 to Malaga, the team that Manuel Pellegrini managed between 2010 and 2013. Pellegrini will be able to get all the inside info on how they did it and also used to work with the winning goalscorer, Juanmi. If Juanmi can slay Barcelona, theres not reason why Sergio Aguero cant follow suit. 3 - NO REASON TO FEAR . City captain Vincent Kompany knows what it feels like to score at the Nou Camp, Joe Hart saved a penalty from Lionel Messi three weeks ago and Yaya Toure won the Champions League with Barca alongside the likes of Xavi, Iniesta, Sergio Busquets, Lionel Messi and Gerard Pique. While the rest of the world regard Barcas players as demi-gods, City have been up against them before and shown they are human, or played with them. Joe Hart saved a late Lionel Messi penalty to keep his side in with a chance of progressing to the next round . 4 - EL CLASICO AWAITS . Coach Luis Enrique wont be thanking La Liga for the way theyve worked out their fixture list because an even bigger match lies in store on Sunday when Barca meet Real Madrid in a potential title decider. The temptation not to play at 100 per cent against City will be there particularly as they already hold a 2-1 advantage from the first leg. It will be up to Pellegrinis side to take advantage if the Barca players have half an eye on the weekend. Barcelona boss Luis Enrique will have one eye on his sides upcoming match against Real Madrid . 5 - CITY BEST IN ADVERSITY . If there is one thing Manchester City have proved in recent times its that they should never be written off. They were eight points behind Manchester United with six games to play in 2012 and won the title. In 2014, they were three points behind Liverpool with three to play, and again came out on top. Most significantly, they have shown bouncebackability in Europe too. They qualified from the group stages despite taking two points from their opening four matches and trailing 2-1 against Bayern Munich in their fifth match. Manchester City showed on the final day of the 2011-12 season that they are capable of springing a surprise . 6 - PROLIFIC AGUERO . Aguero has scored six goals in six Champions League ties this season, at a ratio of a goal every 76 minutes. If he scores again in the Nou Camp, City will be halfway there to overturning the first-leg deficit. Pellegrini believes Aguero has the ability to be considered the third-best player in the world behind Messi and Cristiano Ronaldo. A match-winning performance to rank alongside his hat-trick against Bayern earlier in the tournament would go a long way to making that come true. City forward Aguero hes at the bottom has scored six goals in the Champions League this season . 7 - HISTORY ON THE SIDE OF ENGLISH CLUBS . Its not impossible for English clubs not to be represented in the last eight of the Champions League but history shows its very rare. Only once since 1996 have the quarter-finals taken place without a Premier League team. With Liverpool, Chelsea and Arsenal gone, all hopes rest on City now. They havent always been the most popular team since Sheik Mansours takeover but the club might thrive on the need to restore some national pride. Manchester City are Englands last hope following Arsenals exit from the Champions League on Tuesday . 8 - ALL ROADS LEAD TO ROME . Manuel Pellegrini has been criticised for rigidly sticking to 4-4-2 in Europe and being outplayed in midfield, as he was against Barca in the first leg. But when Aguero was injured for the critical final group game away to Roma, he played Edin Dzeko as a lone striker and City comfortably won 2-0. If Pellegrini repeats the tactics but with Aguero replacing Dzeko and City crowd Barca in the middle of the park, theres no reason they shouldnt threaten the Catalans with the talent theyve got in the team like David Silva. Spanish playmaker David Silva centre may be given the licence to roam if he plays behind Aguero . 9 - MANAGERIAL MIS-MATCH . Barcelona boss Luis Enrique is a Champions League novice as a manager this is his first campaign in the tournament and hes never experienced a knockout second leg. In contrast Pellegrini has guided Villarreal to the semi-final, Malaga to the quarters and took City the Nou Camp last season where they lost 2-1 with 10 men. The Chilean knows what to expect Enrique doesnt. Enrique is a novice when it comes to managing a side in the Champions League knockout stages . VIDEO Barca will attack - Enrique . 10 - YAYA MOTIVATION . Yaya Toure is available for Manchester City are serving a three-match European ban and couldnt be more motivated. For all the stealth of Barcelonas midfield with Ivan Rakitic, Busquets and Andres Iniesta, they havent got the power to live with Toure if he is allowed to run at them. The Ivory Coast international has proved hes a big-match player remember his incredible goal at Wembley in last seasons Capital One Cup final and this could be his defining match in a City shirt. Yaya Toure is available for selection after missing the first leg against his former side through suspension . PS heres three reasons why Manchester City should be fearful of Barcelona .
