Arsenal defender Per Mertesacker confessed that it wasn’t easy to leave Werder Bremen after five years but is now looking forward to a new challenge.

Speaking to Arsenal Player, the Germany International explained that there were many things he needed to learn after switching to English football as compared to the German Bundesliga, the Premier League is very strong, powerful and fast with the 27-year adding confessing that despite his experience in Germany and International football, there’s still room for improvement in his game.

With Thomas Vermaelen suffering a two-month injury in the first part of the season, the tall defender went straight into Arsene Wenger’s starting line-up, doing exceptionally well alongside Laurent Koscielny considering it was the first time the two played together.

On his new “adventure”, Mertesacker said:

[How difficult was it to leave Werder Bremen?] I had a great time at Bremen, I learned many beautiful things, played many good games and yeah, I feel very well there but now comes a new challenge.

[The most difficult part of adjusting to the English league?] I think many, many things, I think English football is very strong, powerful and the speed is much higher than the German Bundesliga.

[My best attributes?] Not so many these days, I hope that the supporters can see what my strengths, what I’m going to be in the next months. Hopefully I can help the team.

I want to improve myself, I think I have to learn a lot here [at Arsenal], I have experience in German football and in the World Cups but this is a complete new situation.

Not an adventure, but it’s for me it’s a new level to play here and my targets and my goals are very high [but yes] I want to improve myself and help the team.
