Arsenal manager Mikel Arteta is unsure when Pierre-Emerick Aubameyang will return to the squad - the Gabonese goalkeeper is reportedly struggling with a personal problem. It reports Sky Sports.

With just a few hours to go, the striker was sent off by the squad that lost 1-0 to Southampton in the English FA Cup yesterday. The club from North London is thus out of the tournament, which they won last season.

The really big question now is when Aubameyang will return again. The Gunners will once again cross blades with Southampton on Tuesday in the Premier League, in an extremely important match for the London club in their hunt for the European-rewarding places in the table. Mikel Arteta himself is in doubt when the dangerous attacker will return

"I do not know. He needs to confront his problem. we will see how it develops." Arteta Said.
