New West Ham United signing Savio Nsereko is determined to repay the faith shown in him by manager Gianfranco Zola.

"Gianfranco Zola was a great player and I think he'll be a great manager," said Savio. "I'll improve a lot under him and try to do my best.

"Both he and Gianluca Nani explained what they want to do here at West Ham with all the young players. They want to improve me and I want to pay them back on the pitch.

"I'm proud to wear that shirt and I'll try to do my best to improve.

The No.10 shirt is a big responsibility but I'll do my best every day.

"Every time I'm on the pitch I'll play with the heart and make the fans happy."
