David O'Leary has won the Carling manager of the month award for the second successive time.
Leeds won all their games last month, beating Southampton, Liverpool, West Ham and Chelsea.
Their league form has been mirrored in the Champions League where they face a crucial semi-final second leg in Valencia next Tuesday.
The Carling panel added: "One can only guess how well David O'Leary's men could have done had they not been hit with so many injuries at the start of the campaign.
"They have strung together a run of 13 undefeated games, and have risen to fourth in the Carling Premiership.
"O'Leary has developed into an astute coach and manager and we expect great things from him in the coming seasons."
