Chris Coleman has promised his team will hold "no fear" when they visit the Premiership leaders, Arsenal, on Sunday.
Fulham pulled off one of the results of the season only a month ago when they beat Manchester United 3-1 at Old Trafford, and they will be hoping for a similar shock at Highbury.
"It will be very difficult, we know that, but we'll go to Highbury and we won't fear Arsenal," the Fulham manager said. "We went to Old Trafford and we didn't fear Manchester United because we don't fear anybody.
"I am not saying we are going to win and I am not saying we are going to play well, but we'll go there with no fear. We've got a lot of confidence in our group and generally when we have played top teams we have performed. Arsenal are a top team but we'll have a go."
Having seen his side climb into fifth place on Monday night thanks to Louis Saha's double in the 2-0 home win over Portsmouth, Coleman is not particularly concerned about facing Thierry Henry.
"He is a world-class player but we played against United and they have Ruud van Nistelrooy who is a world-class player," Coleman said.
"The Premiership is full of them and you play against them nearly every week. Psychologically it was a big result for us to beat Portsmouth. People have said we have done well to get here, but we want to keep it going."
Portsmouth will be hoping for positive news today after their goalkeeper, Shaka Hislop, undergoes a hernia operation. Their manager, Harry Redknapp, is facing a fresh injury crisis and confirmed: "Shaka is going straight in for an operation. He'll be out for a couple of months."
Pompey's first-choice goalkeeper was replaced by the Dutchman Harald Wapenaar, who was making his Premiership debut. It was the first League game that Hislop, 34, has missed since he joined on a free transfer from West Ham in the summer of 2002, ending a run of 58 consecutive League appearances.
"We are short, that's an obvious fact," Redknapp admitted. "I had to put Dion Burton on the bench at Fulham after he came back from a loan at Swindon where he wasn't playing regularly.
"I've got Amdy Faye and Nigel Quashie out injured and Gary O'Neil has gone to join the England Under-20 squad in Dubai. I've got a really small squad and when we get a few injuries problems occur."Reuse content
