The title race will not be decided at the Emirates Stadium but it will play a significant role in the eventual outcome, while Van Persie will want to return to goalscoring form.Sergio Aguero (ankle) believes that he will be fit enough to be at Roberto Mancini’s disposal on Sunday. Joleon Lescott (groin) has recovered from his spell on the sidelines but it would be surprising to see him thrust back into the Manchester City mix for such an important clash.Micah Richards (head) was forced off at half-time in City\'s 3-3 draw with Sunderland last weekend and he could be replaced by Pablo Zabaleta at right-back. Samir Nasri (fatigue) is a likely candidate for a starting role against his former club having missed the last match.Arsenal have a mostly-full-strength squad to choose from ahead of this weekend’s Premier League clash, with their injury list gradually shortening as the climax to the campaign approaches. Jack Wilshere (ankle) remains sidelined, as do fellow midfielders Emmanuel Frimpong (knee), Abou Diaby (hamstring) and Francis Coquelin (hamstring). Defender Per Mertesacker (ankle) will also not feature at the Emirates Stadium on Sunday.
