Mesut Ozil must address his negative body language in order to fully overcome his woes at Arsenal, according to Germany manager Joachim Low.
The German international enjoyed a scintillating start to life in north London following his club record move from Real Madrid as Arsenal stormed to the of the Premier League in its early months.
However, following Christmas Ozil's form drastically dropped and came under severe scrutiny following a particularly lethargic performance against Bayern Munich in the Champions League before he picked up a thigh injury in the return leg that ruled him out for six weeks.
Ozil has been backed by commentators and teammates to overcome his initial struggles in English football and his national team coach believes the playmaker must begin to demonstrate more enthusiasm when things are not going his way to see things improve.
"During his first year at Arsenal he had to learn that football in the Premier League is even more intense and physical than in other league," Low told German magazine Kicker, ESPN report.
"Ozil has been through a low at the end of last year after that the injury followed.
"Mesut needs to work on his body language. He has heard it from me, and, I believe, also from Arsene Wenger.
"He is an inspired footballer. But when he fails or is not able to solve a deciding situation, he also needs to show that he can swallow that and send out signals like, 'In spite of that, I am still here and I can still affect the game.'
He is in the middle of a learning process and he will come out on top. I bank on him and I have complete trust in Mesut Ozil."
Ozil provided glimpses of his former self with performances marked by a goal and an assist in the FA quarter final win over Everton in March and the 3-0 win over Newcastle last month. The former Real Madrid star has started all four of the club's game since his return from injury ahead of their FA Cup final meeting with Hull City.
