Alexis Sanchez was omitted from Arsenal's squad on Sunday to face Bournemouth as speculation mounted over the Chilean's January transfer to Manchester United or Manchester City.
Sanchez, 29, did not even travel to the south coast for the lunchtime kick-off, with Gunners boss Arsene Wenger admitting he was left at home over his unresolved future.
Sanchez has refused to sign a new Arsenal contract with his current deal expiring in the summer, and United and City are reportedly both keen on recruiting the Chile striker this month.
Wenger confirmed before kick-off at Dean Court that he remained unsure on Sanchez's future.
"He's being vague, we have left him at home because of the situation," Wenger told Sky Sports.
"I still don't know what is going to happen."
Wenger admitted on Friday that Sanchez would not be signing a new Arsenal deal, paving the way for him to leave the club in the current transfer window.
