Leeds manager Neil Redfearn told BBC Radio West Yorkshire that his team is 'badly missing' injured midfielder Lewis Cook.
Leeds slipped to a third straight defeat on Saturday, losing 2-1 to Cardiff City having endured a tough Easter period with reverses to Blackburn Rovers and Wolverhampton Wanderers.
However, their cause has not been helped by the recent injury to midfielder Cook, who has been such an integral part of the Leeds team this season.
The 18-year-old defensive midfielder has played 38 games for Leeds this season despite only being promoted from the youth team under Neil Redfearn this term.
Yet now, Cook is on the sidelines having returned from international duty with the England Under-19's suffering from an ankle injury.
Cook has therefore missed the last three games, and it's no surprise that his absence has coincided with the toughest spell of 2015 for Redfearn and Leeds.
After losing to Cardiff City, Redfearn told BBC Radio West Yorkshire that Leeds were missing Cook for all the energy he brings to the team after a dismal display against the Bluebirds.
"He is the one person, in my opinion, that we have so badly missed," said Redfearn. "He gives you desire and energy, he closes down and does other people's jobs, no job's not his own, he'll chase back and we've missed him - big time."
