Dougie Freedman is determined Derby will not profit from Crystal Palace's Carling Cup run for the second time this season
Palace drew 1-1 with the Rams at Selhurst Park last month despite dominating a game which came just 48 hours after their thrilling quarter-final win at Manchester United.
Freedman's men travel to Derby in the FA Cup tomorrow just three days before their semi-final first leg at home against Cardiff but the Palace boss insists the Carling Cup showdown is at the back of their minds.
He said: "It's a little bit of luck for Derby that they catch us so close to a big Carling Cup fixture again but we still have enough in our ranks to put on a good show and win.
"We played really well against them last month but we were a little mentally fatigued after the United match and couldn't hold on. Derby are a very good footballing team when you let them play.
"They beat us 5-0 last season when I was assistant manager under George Burley and we just let them play. We won't be doing that again."
Keeper Julian Speroni is expected to return after recovering from a virus, while Paddy McCarthy is still out with the same illness.
