  "There have been a few players described as 'the new George Best' over the years, but this is the first time it's been a compliment to me."
  
  On 12 August 2003, less than a week after the friendly that impressed Ferguson, Manchester United signed Ronaldo for £12 million, an England record for a teenager. This also made him the first Portuguese player to sign for the club.
  
  Although he requested the number 28, his number at Sporting, he received the squad number 7 shirt, which had previously been worn by such United players as George Best, Eric Cantona and David Beckham. Wearing the number 7 became an extra source of motivation for Ronaldo. A key element in his development during his time in England proved to be Ferguson, of whom he later said: "He's been my father in sport, one of the most important and influential factors in my career."
  
  Ronaldo made his debut as a substitute in a 4–0 home win over Bolton Wanderers in the Premier League on 16 August 2003. His performance earned praise from Best, who hailed it as "undoubtedly the most exciting debut" he had ever seen. Ronaldo scored his first goal for Manchester United with a free-kick in a 3–0 win over Portsmouth on 1 November. On 15 May 2004, in a victory against Aston Villa, Ronaldo scored the opening goal and later received the first red card of his career. Ronaldo ended his first season in English football with a trophy, scoring the opening goal in United's 3–0 win over Millwall in the 2004 FA Cup Final. BBC pundit Alan Hansen described him as the star of the final. The British press had been critical of Ronaldo during the season for his "elaborate" step-overs in trying to beat opponents, but teammate Gary Neville said he was "not a show pony, but the real thing", and predicted he would become a world-class player.
  
  "He has got the tricks and party pieces, we know that, but they're not much good unless there is something at the end of it all. We still have to remember, of course, that the lad is only 19 years of age. Considering that, you have to say he has got massive talent. His feet are mesmerising at times, and if he can couple that with some consistently good crossing, the future looks frightening."
  
  At the start of 2005, Ronaldo played two of his best matches of the 2004–05 season, producing a goal and an assist against Aston Villa and scoring twice against rivals Arsenal. Ronaldo won his second trophy in English football, the Football League Cup, after scoring the third goal in United's 4–0 final win over Wigan Athletic.
  
  During his third season in England, Ronaldo was involved in several incidents. Ronaldo clashed with a teammate, striker Ruud van Nistelrooy, who took offence at the winger's showboating style of play. Following the 2006 FIFA World Cup, in which he was involved in an incident where club teammate Wayne Rooney was sent off, Ronaldo publicly asked for a transfer, lamenting the lack of support he felt he had received from the club over the incident. United denied the possibility of him leaving the club. Although his World Cup altercation with Rooney resulted in Ronaldo being booed throughout the 2006–07 season, it proved to be his break-out year, as he broke the 20-goal barrier for the first time and won his first Premier League title.
