I don't feel like I have anything to prove to the fans in England - but I know that in England they did not see the best of me.
There is no question that Notre Dame has the best, biggest and finest name in college football.
It's very interesting to observe how highly the Bundesliga is spoken of abroad, from the overall quality to the stadiums, the family-friendly atmosphere, and the football itself.
Back home in Germany, football people think very highly of Arsene Wenger. They listen to what he has to say and admire his achievements.
You know I don't think there will ever be a time when the English player is not respected, and feared, across the world of football. The English footballer is very brave and strong and committed and there is always enough high-class players in his team to cause concern in any opponent. It is a national characteristic.
In Ukraine as well as in Brazil, Manchester City is now considered one of the best teams in the world, and after I signed, people back home in Brazil congratulated me for signing for one of the top teams in the world.

Ligue 1 is much stronger than people give it credit for.
Celtic and Ajax are great names in history. They both have great followings all over the world, not just in Holland and Scotland.
I don't know why I keep getting roped in with the so-called 'bad boys' of football. I really don't care, either.
