Per Mertesacker says he is happy with the way he has adapted to life at Arsenal following his summer move from Werder Bremen.
Mertesacker was thrown in at the deep end following his summer switch as an injury crisis and big-name departures combined to consign Arsenal to their worst ever start to a Premier League campaign.
However the Gunners recovered from their perilous position and can secure third place with a win against West Brom in their final game of the season.
Mertesacker's career at the Emirates has followed a similar trajectory with the German international winning over his critics before a season-ending ankle injury against Sunderland back in February.
The 27-year-old admits that while the change in pace to life in the Premier League was initially difficult, he feels he was getting up to speed before his season was bought to an abrupt end.
"Sometimes I felt like it was very hard, especially when I first came here," Mertesacker told Arsenal Player.
"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."
He added: "In general you are playing the best players in the world. You always have to perform at a high level.
"It is at a constant level and that is what makes the Premier League so good and so sharp."
Despite his injury Mertesacker was named in Germany’s provisional squad for the European Championships this summer over the weekend.
