Harry Redknapp admits to still being in amazement at witnessing what he describes as ‘one of the great European' performances from tonight's opponents Fulham last week.
The manager was at Craven Cottage to watch Roy Hodgson's side come back from a 4-1 aggregate deficit to defeat Italian giants Juventus in the Europa League.
It was a result Harry admits he and his players could only sit back and admire as they prepare to face the Cottagers for a place in the semi-finals of the FA Cup tonight.
So he knows we will have to be on top of our game in front of what is expected to be a packed house at the Lane to prevent Fulham repeating last Thursday's heroics.
Harry said: "We have a mighty tough game on our hands. I was fortunate enough to be there last week to watch them beat Juventus.
"It was one of the great European performances of all time. It was a fantastic night, a great atmosphere and a great performance from Fulham, so this will be a really tough match.
"I have so much respect for Fulham, and my players all saw the game last week and were talking about it the next day. So this is one of the toughest games we could pick as they are a really good side."
And Harry puts Fulham's marked improvement over the last two years down to his much-respected opposite number, Hodgson.
"He has done a great job there for the last couple of years. He is a terrific guy who knows the game inside out and he has been a terrific signing for Fulham. He has taken them upwards and built a very good team there.
"It is good that Roy came back into the game after being out in the cold for so long since his days at Blackburn. It shows what he can do. It is about giving people opportunities."
