Simon Grayson insists old club Leicester City will be firmly in the promotion mix come the business end of the season – despite the Foxes currently residing in a disappointing 16th spot.
Grayson admits he is desperate to turn over his former employers – the opponents in his first match in charge of United on Boxing Day 2008 – with the Midlanders somewhat of a bogey side for Leeds.

City, play-off semi-finalists last term, boast a seven-match unbeaten streak against United, who have also never tasted victory at the Walkers Stadium in five attempts.

That said, City's form has been chalk and cheese this term, with their travel sickness comparing markedly with their impressive sequence at home, which has yielded six wins in 11 games.
Grayson said: "They have certainly got a fantastic manager and players who are capable of taking them out of this division.
"They gave us a tough time when we played them earlier this season and they beat us 2-1. And obviously, the rumours have it that they will be going big in the transfer market in January.
"They've certainly done that with their loan signings when you look at Curtis Davies, (Darius) Vassell and (Roman) Bednar – all Premiership players.
"They won't be far away. They have had a few inconsistent results away from home. But at home, they are a major threat.
"We know it's going to be difficult, but I'm sure they are aware of what we've done over the past nine games. It's about time we beat them, so hopefully I won't have too many friends at the Walkers Stadium on Sunday!"
Meanwhile, Grayson has confirmed he will shake things up over the four-game holiday programme.
He added: "We've got some players who are desperate to get some time on the football field who have not had that opportunity in the past few weeks or since we signed them in the summer.
"Over the course of this period, there will be individuals who do play large parts of every game, because of the positions they play. Others certainly won't be able to play back-to-back games because of their position."
