Podolski insists he will be ready to hit the ground running when he moves to the Gunners this summer.
"At the time the transfer negotiations started between the two clubs, the decision was made really quickly. I'm now looking forward to the challenge at my new club and cannot wait to start after Euro 2012.
"I had a very good season with Cologne, I played well and as a result I'm now going to Euro 2012 with lots of confidence.
"After that, I will be joining up with my new team-mates at Arsenal and it is my goal just to do my best and be successful there."
