Tottenham's assistant manager Gustavo Poyet, has slammed the decisions of the referee, which he feels cost his side an important away win against West Ham.

The Hammers held on at Upton Park to earn a 1-1 draw, but Tottenham could have stolen all three points, when Robbie Keane appeared to be hauled down in the area by Rob Green, but nothing was given.

Jermain Defoe could have made certain of a win in the closing stages, against his former club, but his penalty was saved by the controversial West Ham keeper, to the dismay of the Tottenham coaching staff.

Poyet told BBC Sport, "I'm not happy but we are not going to talk about the ref.

"I think it was a penalty [when Robbie Keane was fouled] and a red card [for Robert Green]. That would have been a big change for the rest of the game."

He added: "I think we did enough to win it. We are a little bit disappointed but that is football. We are still unbeaten and we have to keep going."
