Arsène Wenger has said his future will probably be decided in the spring as he ponders whether to take up the offer of a contract extension or leave Arsenal at the end of the season.

Wenger was speaking to the German TV station ZDF before Arsenal’s 5-1 Champions League defeat by Bayern Munich on Wednesday, but details of the interview emerged only on Thursday.

Asked when he would decide whether to continue, he said: “March, April probably.”

The 67-year-old was stunned almost into silence after Wednesday’s game, answering only three questions in a press conference that lasted under three minutes. The manager is due to speak publicly again on Friday.

Arsenal’s next match is in the FA Cup at non-league Sutton United on Monday. Alexis Sánchez is expected to miss that game after flying out from Heathrow airport on Thursday. It is understood the player has been given leave, though the club declined to comment.
