Arsenal boss Wenger admits he may buy in January
Wenger is not ruling out some transfer activity at Emirates Stadium but he is keen to keep expectations at a realistic level.
"Robin Van Persie is a very, very long-term injury and we are open-minded on the transfer market," said the Arsenal manager.
"But I don't want to promise things that I don't really know I will do at the moment.
"Mainly I am expecting our players to come back [from injury]."
