Ozil, 25, became the most expensive German player ever when he left Real Madrid to join the Gunners on the final day of the summer transfer window in 2013.
He came in for scrutiny when he missed a penalty against Bayern Munich in the first leg of the Champions League last 16 game against Bayern Munich. His contribution in the second leg was also questioned before he was withdrawn with a torn muscle at half-time.
Ozil returned to the Arsenal team in late April, and has recently said that he is fully satisfied with his first year at the Emirates.
Loew has said that Ozil needs to show greater strength of character at times, but has backed him to overcome the challenges of adapting to English football and to become a better player for it.
He told kicker:"During his first year at Arsenal he had to learn that football in Premier League is even more intense and physical than in other leagues. Ozil has been through a low at the end of the 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."
