On 27 August 2010, Atlético Madrid captured the UEFA Super Cup by beating favorites Inter Milan 2–0. Agüero provided the assist for José Antonio Reyes' opening goal and then secured the win by scoring the second. On 4 January 2011, Atlético Madrid confirmed via their official website that Agüero had signed a new contract which would keep him at the club until 2014. The following day, he was named as the new vice-captain of Atlético, along with strike partner Diego Forlán. The 2010–11 season was arguably Agüero's most successful for Atlético, as he scored 20 league goals for the first time in his career. Between March and May 2011, he went on a run of seven consecutive goalscoring appearances, a feat that no other player in Europe could match during the season. Agüero's final outing for Atlético came on 21 May against Mallorca, a game in which he reached two milestones. In a 4–3 win, he scored his first career hat-trick, the second goal being his 100th for the "Colchoneros". Failure to celebrate any of the goals, however, led to speculation that he would be on his way out of the club.
