Andy Johnson has vowed to step up and find the target for Fulham in the absence of Bobby Zamora.

Zamora has led the line with distinction at Craven Cottage this term having endured a disappointing goal return in his first season with Roy Hodgson’s side. The former West Ham striker has already scored 11 goals for Fulham and his impressive form has fuelled talk of England call-up. But Zamora could be out for as long as eight weeks after dislocating his collarbone in Tuesday’s defeat at Stoke.

Johnson, who himself has missed a similar spell this season due to shoulder and groin injuries, has just returned to the Fulham side having made his first league start since August at the Britannia Stadium. The England international knows he will have to step up to fill the void created by Zamora’s absence with Diomansy Kamara still a couple of weeks away from full fitness.

That [losing Zamora] was a massive blow for the team. He’s been fantastic and in the form of his life. His confidence was flying so it’s up to me, Erik and Diomansy Kamara to carry on what Bobby’s been doing.

He’s been fantastic and he’s going to be missed. The boys have got to step in now.

It will be interesting to see how Hodgson decides to shuffle his pack for Saturday’s visit of Portsmouth. Clint Dempsey scored a wondergoal as a second half substitute at Stoke and could play as a makeshift striker alongside Johnson, although Erik Nevland scored twice for Fulham against Portsmouth at the Cottage last season and will be keen to stake a claim for a starting spot.
