Avram Grant is confident that goalkeeper Robert Green will put his poor form behind him to play a key part in West Ham's battle for survival.
A costly error against Chelsea and a fumble against Stoke last weekend following his gaffe for England in the World Cup have done little to ease the fears surrounding Green's ability to deal with the psychological pressure of being targeted by away fans during matches.
However, Grant said: "I don't know of one player who is good all the time. It's especially bad with goalkeepers because everyone is watching but after five games I don't want people to make a judgement about Robert Green."
Green's summer was blighted by the horrific error which handed the United States a valuable point in England's World Cup opener in Rustenburg.
Fabio Capello has not picked Green since, while the former Norwich stopper's domestic performances have been far from the level which saw him become England's number one last season.
Czech Republic Under-21 stopper Marek Stech replaced Green in goal against Sunderland in Tuesday's Carling Cup win - West Ham's first of the season - but the 30-year-old is expected to return for tomorrow's Barclays Premier League clash with Spurs.
Grant seems baffled by the scrutiny over his number one's performances and is confident he will have a successful campaign. "Every player has their good days and their bad days," he said.
"I have a feeling that we will look back at the end of the season and say he had a good year."
