Saying goodbye is very emotional.
Going from a two-year-old Polish boy, who practically came to Germany with nothing more than a football under his arm, to a world champion - it's more than I could have ever imagined.
I had other interesting offers, but for me, it had to be a top club. When you look at Arsenal, with a fantastic manager, good environment, and never any bad press surrounding the club, they are playing attractive football and have a great stadium with great fans.
