The obvious change has been made. With Manchester United playing deeper since scoring their second goal, Arsène Wenger has brought on Marouane Chamakh - somebody who will give the Gunners a presence within an ever-crowding United area. Denilson has been sacrificed.
The Brazilian made no impact on the match, and with Manchester United conceding the midfield battle, Chamakh for Denilson was the obvious choice. Jack Wilshire will likely play slightly deeper to pick up some of the distribution Denilson was supposed to promote. The narrowing United defense will now have to worry about Chamakh's presence as Bacary Sagna and Kieran Gibbs go wide and get behind the Red Devils' line. Robin van Persie will also be freed-up from his responsibilities along the line, his strong left foot free to try from distance, hopefully loosening United's defense.
Still, van der Sar has not been threatened since Laurent Koscielny's early second half chances, and with the match assuming a posture that we're seen all too often in recent United-Arsenal meetings, the surfacing question is why we should expect this match to be different. Just after the hour, we're given little reason to think so.
