Arsene Wenger will keep Arsenal sweating about his future until they have qualified for the next phase of the Champions League.
Although Arsenal are confident that Wenger will sign an extension to his existing £7.5million a year deal, the Frenchman has yet to commit.
Wenger, who turned 64 last month, does not want his contract negotiations to become a distraction during a difficult run of fixtures.
Arsenal face a tough test against Borussia Dortmund on Wednesday before travelling on to Manchester for their clash with the champions at Old Trafford on Sunday.
They finish off a difficult Champions League group with games against Marseille and Napoli and Wenger is expected to wait until then before making a decision on his future.
Both parties remain relaxed about Wenger's contractual position, but owner Stan Kroenke and chief executive Ivan Gazidis have both made it clear that his future is at Arsenal.
