Manager Kevin Blackwell has conceded time could be running out for Sheffield United in their late charge for the play-offs.The Blades secured a sixth win in their last eight league matches at Burnley over the weekend, but remain five points behind sixth-placed Crystal Palace, who beat Scunthorpe, with three games remaining.

Blackwell said: "We've got to believe we still have a slight chance as everyone in contention is beating each other, with the possible exception of Palace.

"I just wish we had an additional four games left to play because that would make things very interesting.

"But it's nice to be entrenched inside the top 12 after spending so long winning but not getting any closer to those above us in the table."
