I went through a lot of good moments in Arsenal and a lot of difficult moments as well.
I know, everywhere I go, I have the door open because I am a great footballer and a great person.
I never regret making a decision.
If I regret leaving City, I'd regret leaving Madrid, I would regret Arsenal, and I would regret maybe even Metz, where I started off. So I have no regrets in life; life is too short to start regretting things.
If you are Cesc, going to Barcelona, he will make more money, more sponsorship, and he is going home. What did Arsenal do to keep him at the club? Absolutely nothing. Now the fans say he is not loyal. When you leave Arsenal, you become a traitor, regardless of what you have done.
I enjoyed my time at White Hart Lane, and I can't say thank you enough to the Spurs fans.
The best coach I have ever worked with is certainly Jose Mourinho. He has an unparalleled passion.
I plan with the BBC African Player of the Year award to become an agent of hope and positive change in the lives of the millions of African youths who have lost hope and are deprived.
