“Everything has been done that we possibly can”, McFarlane told the club’s official website.
“We’re working really hard to make sure the lads are as best prepared as they can be for what Leeds are going to throw at us, and we know what we have to stand up to.
“They’re a really good side that can cause you a lot of problems, and we know the challenge we face, but the players are motivated to get to an FA Cup final.
“Everyone’s on board, and we’re ready.”
Daniel Farke’s side cannot squander this opportunity
Chelsea have found Daniel Farke’s Leeds United a difficult side to deal with this season. They lost 3-1 at Elland Road and were later held to a 2-2 draw at Stamford Bridge in February.
Leeds have made those meetings count, taking four points from six against a long-standing rival.
The mood around this semi-final has shifted, though, particularly after Chelsea parted ways with Liam Rosenior. That decision has led many to rethink how the game at Wembley could unfold.
Semi-finals always come with pressure, and Chelsea still have players who are used to the big stage. However, their dip in form, doubts over confidence and fitness, and the recent managerial change have added a layer of uncertainty.
Those earlier results will still be fresh in the memory, and Leeds will head into the game believing they can get the job done. Right now, they are increasingly being seen as slight favourites to edge past the Blues.
This is Leeds’ chance to reach an FA Cup final for the first time in 53 years, and they must not squander it.
