The mentality with African and European people is different. In Africa, when you come from a difficult life, when it's not so easy to eat, not so easy to survive, you respect money when you start to earn it, and you respect people more. When you respect people, they will respect you, and your life is better for that.
When you spend a lot of money on one player, you want him to prove himself, but the way football works, one day you can be good, the next you can be bad, and the next after that, you can be very bad. I have come to Manchester City to work very hard and to help my friends make Manchester City great.
