Arsenal defender Shkodran Mustafi says it's clear that Mesut Ozil is responding to the methods of manager Mikel Arteta.

Ozil has endured a difficult season at Arsenal and under former head coach Unai Emery his future was uncertain after falling out of favour.

However, the appointment of Arteta, who played alongside Ozil at Arsenal for three years, has reignited the ­German playmaker.

Mustafi said, “Mesut is a good friend of mine and I know him very well," said Mustafi, who was also part of Germany's squad that went all the way in Brazil five years ago.

“I knew him before his time at Arsenal and I know what he is capable of. For him, and a lot of other players, the change that we had with the boss helped him a lot, as it helped a lot of other players.

“When the team is performing well, it is easier when everyone knows how we want to play. You can focus on your job and you don't have to care about a lot of other things because everyone is doing their job and knows what to do. You can focus on yourself.

“For him, now, because we want to play football, we want to play attacking football, it suits him. He enjoys himself and when he is playing like he has in the last few games it helps the team."
