LONDON, Nov 27 - West Ham United's Argentina forward Carlos Tevez apologised on Monday for walking out on his team mates after being substituted at the weekend.

Tevez, who along with World Cup team mate Javier Mascherano was a surprise transfer coup in August, stormed out of Upton Park on Saturday after being taken off by manager Alan Pardew in their 1-0 win over Sheffield United.

"I would just like to say that I left the ground in anger on Saturday, it was a spur of the moment decision which I regretted almost straight away," Tevez said in a statement on the club's Web site www.whufc.com.

"I know I did very wrong in going and I have made it clear to the manager and my team mates that I in no way meant to disrespect them."

The club said the 22-year-old apologised to Pardew and the rest of the squad when they met up on Monday for training.

Pardew said: "He knows he made the incorrect decision in leaving and has decided he would like the players to vote on how much his fine should be and that it should go to the Great Ormond Street Hospital.

"The players will be given the chance to offer their opinions tomorrow morning."

Tevez, though impressive with Argentina, has struggled to settle in to the pace and physical combat of Premier League football and has yet to score for his new club.
