The assistant manager has warned the Reds to expect a tough game at Turf Moor as Burnley fight for their Premiership survival.
"At the end of the day we are still fighting for what we want. We've said on many occasions that each game presents its own degree of difficulty and none more so than Burnley," said Lee.
"It's a very difficult place to go. The pitch won't be great but we'll have to adapt to it.
"We know they have Fletcher who has scored some goals for them this season, but they also have Nugent and we know he can be a threat for us. At the end of the day it's about how we approach the game and we have to make sure we do everything right from our end."
