Arsene Wenger believes Sunday's crushing victory over Manchester City could be a key point in Arsenal's season.
The Gunners went into the match five points behind league leaders Chelsea and needed victory at Eastlands to stay in touch with their London rivals.
And Wenger's side succeeded, securing a 3-0 victory courtesy of goals from Samir Nasri, Alex Song and Nicklas Bendtner after City had Dedryck Boyata sent off in the fourth minute.
