Flamini, however, did indeed sign for Arsenal on 29 August 2013 and became Arsenal's second acquisition of the summer, after Yaya Sanogo. He made his returning debut on 1 September at Emirates Stadium against Tottenham Hotspur, coming on for Jack Wilshere and helping the team secure a 1–0 win. His performances after signing were lauded by both critics and fans alike, and had featured in all of Arsenal's Premier League, Football League Cup and European games since, with many seeing his signing, and his combative style of play, as one of the key reasons for Arsenal's excellent early season form. He scored his first goal in his second spell at Arsenal on 30 November, the second in a 0–3 away win at Cardiff City. He has also scored in a crucial 1–1 draw against Manchester City after a run of bad form from Arsenal, helping the club rejuvenate and achieve an eventual top four league finish. At the start of Arsenal's 2013–14 FA Cup run, Flamini expressed his desire to win the Cup, having been left out of the squad when Arsenal won the 2005 FA Cup Final. Arsenal went on to win the tournament, though Flamini was an unused substitute in the Final, also remaining on the substitutes' bench when Arsenal repeated the feat, becoming FA Cup champions again in 2015.
