Sam Allardyce has encouraged his West Ham United team to be more ruthless in future outings following a 2-0 win over Queens Park Rangers this afternoon.

Nedum Onuoha's own goal after five minutes helped the Hammers into a slender half-time lead before Diafra Sakho doubled the advantage on the hour mark.

However, Allardyce has suggested that the manner of victory might have been more comfortable had his troops gone for the jugular.

"I think that we were very comfortable, except perhaps for 10 minutes into the second half when they changed their system and we didn't really come to terms with it," Allardyce told Sky Sports News.

"If I was to have a little bit of a criticism, it would be for not punishing them enough with the amount of times we were in or around the final third.

"Perhaps we could have done a little better with those opportunities, but that's being ultra greedy on the basis that we've won very comfortably and kept a clean sheet, which is what I've been striving for, because you can't score two or three goals every game to win."

Victory over Rangers lifted Allardyce's side up to seventh in the Premier League table.
