Walsall boss Colin Lee says his side face a massive task if they are to pull off another FA Cup upset against Fulham at a sold-out Bescot.
Walsall beat Charlton Athletic at The Valley in the fourth round but Lee believes that the team will have to raise their game to new heights if they want to see off big spending Fulham.
Lee, who tasted defeat for the first time as Walsall manager last weekend when they were beaten by Sheffield Wednesday at Bescot, had Fulham watched in their last game at Blackburn Rovers and the report that he received only confirmed everything that he already believed.
The former Watford and Wolves' boss said: "This is going to be a very tough game for us as there is no doubt that Fulham are a quality team.
"I had them watched at Blackburn last Saturday and they beat Blackburn quite comfortably - you have to be a good side to do that.
"Fulham play a different type of game to Charlton and they can cut you open with the way that the pass the ball.
"We have to make things as difficult as possible for them - we must be organised when they get the ball and positive when we get it.
"After what we did at Charlton, Fulham will know they have to perform and we won't be able to catch them unawares."
