Yakubu said: "I wanted to move to a club which had ambition and at the moment Everton have ambition. They are fighting for trophies and they want to finish in the top six and play in Europe.
"Before the end of last season I had made up my mind to leave. It was a blow to lose Mark Viduka, because he was a great player who I enjoyed playing with. He is a great person, too. I wanted to carry on playing with him but it was not possible.
"I would not say anything bad about their players, but I just wanted to play for a club that was in Europe and I am enjoying my football at Everton. I am lucky to be there. I am really happy.
"We are chasing a trophy in the Carling Cup and if we can win something that would be a great season both for me and the club. I moved at the right time and made the right decision to go. I don't regret it.
"It is disappointing when you play for a club, then you leave and come back and the reception is bad. You have to cope with it as a footballer and you have to accept it. And I did expect it."
