Sheffield United manager Chris Wilder expects the battle for promotion to the Premier League to go all the way.
With 10 games of the Championship season to go the Blades are level on points with table-topping Leeds United and two points ahead of third-placed Burnley.
Wilder's side were five points behind the Whites just two weeks ago when Daniel Farke's men came back from behind to win 3-1 at Bramall Lane.
"This is going to be how it is right the way through, I've said all along it's an accumulation of points," he told BBC Radio Sheffield.
