West Ham manager Gianfranco Zola says he is delighted by the form of youngster Jack Collison.

The 19-year old scored the winner for the Hammers against Manchester City on Sunday and Zola praised his performance.

"That is the beauty of football. Sometimes if you have passion and if you have belief you can be successful and I think Jack Collison is an example of all of that," Zola said.

"Jack is unbelievable, he's getting better and better. He's 19 and he's playing nearly every week. He's got a very good attitude and he is going to get better and better.

"I feel very lucky to have him. Not only him but other players. that's why I like the attitude here," the Italian added.

"I can play them in different positions. As long as you know how to play football you can still produce and be important for the team. I'm sure I could play Jack Collison up front or right at the back and he could still produce good results for the team."
