Career

Barcelona

Messi played in Barcelona's junior Infantil B and Cadete B & A teams from 2000 to 2003 (scoring 37 goals in 30 matches in Cadete A). Season 2003–04 saw him in record five different teams: He started one match in Juvenil B (one goal) and got promoted to Juvenil A (14 matches, 21 goals). Later he debuted for FC Barcelona C team (Tercera División) on 29 November 2003 and for FC Barcelona B (Segunda División B) on 6 March 2004. He played for both teams during the season (eight matches, five goals and five games, zero goals, respectively). Even before these two debuts, Messi made his official debut for the first-team on 16 November 2003 aged 16 years and 145 days, in a friendly match against Porto.
Less than a year later the debut, Frank Rijkaard let him make his league debut against RCD Espanyol on 16 October 2004 (at 17 years and 114 days), becoming the third-youngest player ever to play for Barcelona and youngest club player who played in La Liga. This record was broken by Bojan Krkić in September 2007. When he scored his first senior goal for the club against Albacete Balompié on 1 May 2005, Messi was 17 years, ten months and seven days old, becoming the youngest to ever score in a La Liga game for Barcelona until it was again broken by Bojan Krkić in 2007, scoring from a Messi assist. Messi said about his ex-coach Rijkaard: "I'll never forget the fact that he launched my career, that he had confidence in me while I was only sixteen or seventeen." During the season, Messi played also in Barcelona B (Segunda División B) scoring 6 goals in 17 matches.

In June 2004, he debuted for Argentina, playing in an under-20 friendly match against Paraguay. In 2005 he was part of a team that won the 2005 FIFA World Youth Championship in the Netherlands. There, he won the Golden Ball and the Golden Shoe, scoring in the last four of Argentina's matches and netting a total of six for the tournament.
He made his full international debut on 17 August 2005 against Hungary at the age of 18. He was substituted on during the 63rd minute, but was sent off on the 65th minute because the referee, Markus Merk, found he had headbutted defender Vilmos Vanczák, who was tugging Messi's shirt. The decision was contentious and Maradona even claimed the decision was pre-meditated. Messi returned to the team on 3 September in Argentina's 1–0 World Cup qualifier away defeat to Paraguay. Ahead of the match he had said "This is a re-debut. The first one was a bit short." He then started his first game for Argentina against Peru; after the match Pekerman described Messi as "a jewel".
On 28 March 2009, in a World Cup Qualifier against Venezuela, Messi wore the number 10 jersey for the first time with Argentina. This match was the first official match for Diego Maradona as the Argentina manager. Argentina won the match 4–0 with Messi opening the scoring.
On 17 November 2010, Messi scored a last-minute goal against South American rivals Brazil after an individual effort to help his team to a 1–0 win in the friendly match, which was held in Doha. This was the first time that he had scored against Brazil at senior level. Messi scored another last-minute goal on 9 February 2011 against Portugal in a penalty kick which he give his side a 2–1 victory in the friendly match, which was held in Geneva, Switzerland.
