Chelsea coach Carlo Ancelotti believes striker Salomon Kalou will play an important part in the future of the club after the Ivory Coast international signed a new three-year contract.
Kalou follows Didier Drogba, John Terry, Ashley Cole, John Mikel Obi, Florent Malouda, Hilario and Michael Mancienne in agreeing new deals since the end of last season.
Kalou's new deal will keep him at Stamford Bridge until 2012 and is believed to be worth around £60,000 a week.
"I am very pleased that Salomon has signed a new contract with us as he is an important player for this club," said Ancelotti. "He is always well motivated and works hard at his game at all times. Because of this I am sure that Salomon will become an even more important player for Chelsea in the future."
Kalou, 24, is in his fourth year at Stamford Bridge and has made 93 starts, 66 substitute appearances and scored 31 goals. During that time he became an international and at the weekend was part of the Ivory Coast side that qualified for the World Cup finals in South Africa next summer.
His contract was set to expire at the end of the season but Chelsea moved quickly to tie the striker down on a longer contract after FIFA imposed a transfer ban on the club.
