Arsenal host Crystal Palace on Sunday afternoon knowing that three points will see them return to the top of the Premier League table.
Manchester City and Chelsea don't play until Monday, so the Gunners can establish a two-point advantage over Manuel Pellegrini's side with a win over Palace.
Mathieu Flamini is suspended for the match at the Emirates Stadium, but Kim Kallstrom could be included if he completes a move on Friday.
Manager Tony Pulis has guided Palace to four wins in their last eight fixtures, but he will be aware that his side will be up against it in North London.
Pulis could name an unchanged starting lineup, but Joe Ledley and Scott Dann could feature if they secure moves from Celtic and Blackburn Rovers respectively.
