Arsene Wenger feels Theo Walcott must soon make a "concrete" commitment to Arsenal if he wants to stay at the club.
The England forward, currently sidelined by a shoulder problem, is out of contract at the end of the season, and so could open talks with foreign clubs in January.
"Ideally he has to commit. It is difficult. I believe you have to commit at some stage," said the Arsenal manager.
