Arsene Wenger hopes for a clean bill of health when his Arsenal stars return from the international break.
When they do get back to domestic duties, against Wigan at Emirates on 24th November, they will have to make do without Cesc Fabregas, whose needless late caution at Reading will see him serve a suspension.
"We wanted to get back in charge of this league. We have a game in hand, and so at the moment it is going well," said Wenger, whose team are ahead of United on goals scored.
"Now everybody goes on a break and then we play Wigan at home.
"The international programme of the players is quite heavy for some of them.
"We lost [Cesc] Fabregas with suspension now for Wigan, so let's hope everybody comes back without injury because we lost van Persie during the last break and he still has not played yet."
