Mesut Ozil is unhappy at Arsenal amid his ongoing messy situation, admits close friend and team-mate Sead Kolasinac.
World Cup winner Ozil has found himself cast in the dark this season, dropped from Unai Emery's plans and often unable to get a place on the substitutes bench.
Ozil continues to train with the Arsenal first team, though has made just a single Premier League appearance all season.
'Mesut is a really driven player,' Kolasinac said during an interview on Premier League Productions.
'He is a bit unhappy at the minute but you would never see that in his training. He is doing everything he can. He is doing extra sessions to make sure he is at the level he needs to be.
'Mesut is Mesut. He has got a lot of special qualities.
'For example, the opposing team might put two players on him rather than one, which creates a lot of space for others. That makes a real difference on the pitch and in the game.'
