In August 2010, Wenger signed a further three-year contract to continue his managerial career at Arsenal. His team were on course for a quadruple trophy haul in 2010–11, before defeat to Birmingham City in the 2011 Football League Cup Final, when a mix-up between goalkeeper Wojciech Szczęsny and defender Laurent Koscielny allowed Obafemi Martins to score the winning goal. This was followed by a run of just two wins in 11 Premier League games, to take them from title contenders to a fourth-place finish. Arsenal then made exits in the FA Cup and the Champions League to Manchester United and Barcelona, respectively.
