Fulham fit-again midfielder Lasse Vigen Christensen will relish the chance to knock Sunderland out of the FA Cup in next Tuesday’s fourth round replay.

Christensen returned from four matches out with a hamstring problem to help the Cottagers secure a second crack at the Premier League Black Cats.

“We need to just come out like we did at their place and not give them too much respect,” said the lively 20-year-old.

“We can show them what we can do. We had a young team (on Saturday), but the two boys up front (Moussa Dembele and Cauley Woodrow) worked hard, kept the ball and caused Sunderland problems all day long.

“We changed the starting XI a bit, but it showed we have a strong team. Sunderland will need to be at their best at the Cottage to get a result.”

On his return to the side, Christensen says he “felt good” but admitted to feeling tired after the match.

“You lose that little edge when you’ve been out for a few weeks,” the midfielder said.

“The medical boys have given me a hard time and kept me fit but sitting on a bike in the gym is never going to be the same as playing actual games.

“I’m not feeling my hamstring, though, and I’ve got 90 minutes in my legs. I tried to come back too soon and had to go off against Wolves. You learn as a player with those kind of injuries and I’d never really had one before.

“So I had a bit of extra time on the sidelines and did some more prevention work to make sure I was fully fit. I feel strong. I maybe just need a few more games before I’m back at 100 per cent.”
