The central defender has had a shaky start to his time at the Emirates, but depsite this has stated that he is happy in England and is starting to feel at home in London
The Germany international has been thrown into the deep end in the Premier League, deputising for the injured Thomas Vermaelen in a struggling side.
Despite the poor start to his time in north London, the 27-year-old is glad to be playing with Arsene Wenger's team.
"I always wanted to play for the club, I am so thrilled. Now that I'm right in the middle of it, there grows a sense of pride that I am actually now a part of this club," he told Weser-Kurier.
"I of course [think about] Werder Bremen. But I can assure you that I do not regret this move to Arsenal, and I will never regret it.
"This is a decision that will bring me 100 per cent forward. Our team is very, very good and can compete in the Champions League," he concluded.
Joachim Low will hope Mertesacker's form improves, as Germany will look to the defender to play an important part in their bid for European glory at Euro 2012 in Poland and Ukraine.
