Per Mertesacker has revealed that he is pleased with the way that he has adapted to life at Arsenal.

The German international joined the Gunners last summer from Werder Bremen.

Despite admitting that he struggled to adapt to the Premier League at first, the 27-year-old has now insisted that he feels "very comfortable" at the Emirates Stadium.

"Sometimes I felt like it was very hard, especially when I first came here," Mertesacker told the club's official website.

"It was tough to settle down [and I was] very quickly into the first squad. There was sometimes a lack of performance but I think you have to go through that to improve yourself.

"I am very comfortable here now, and very proud to be with this club."

Mertesacker is currently on the sidelines with an ankle injury.
