Gianfranco Zola, one of the greatest overseas players to grace the English game during his seven years at Chelsea, was named as the new manager of their Premier League rivals West Ham United on Thursday.

The 42-year-old, who signed a three-year contract, also had a glittering international career with Italy and was working as assistant coach to the Under-21 Italy side before deciding to accept West Ham's offer and move back to London.

He replaces Alan Curbishley, who resigned a week ago because of too much board interference.

Although he is the Hammers' fifth manager in seven years, he is the first foreigner to manage the club which remains closely linked to their working-class, east London roots.

"In my first experience in England I had seven wonderful years with Chelsea, and that is something I will never forget," he told a news conference when he was unveiled as the new boss at Upton Park on Thursday.

"But now I have the possibility to have another great experience as a manager and I hope my next few years will be as good as my first seven. That's my aim, my target.

"I will do everything I can, with all my power, to make it work. This is a very important part of my life and what is important is this club which has put their faith in me and I will try to make it work for them."

West Ham said Zola was the unanimous choice of the board who had drawn up a list of "high calibre" candidates.

"I am very delighted, it's a great honour to be given such an important job," he added.

"I thank the board for choosing me and Gianluca Nani for supporting me."
