Manager: Former Leeds player Simon Grayson returned to Elland Road just over a year ago with the mandate to win promotion back to the Championship. And, after last season's play-off disappointment, his side are well placed to do just that this year. Grayson's managerial career began at Blackpool, whom he guided to League One play-off final glory in 2006/07. His switch to Leeds did not run smoothly as the Seasiders threatened legal action after refusing to accept their manager's resignation.
Referee: Chris Foy has taken charge of two games involving United this season – the Community Shield encounter against Chelsea and October's League Cup win at Barnsley, in which he issued five yellow cards and also sent off Gary Neville.
Rivals watch: All the big guns are in third-round action. On Saturday Liverpool travel to Reading and Middlesbrough welcome Man. City, while holders Chelsea host Watford on Sunday and Arsenal visit West Ham in one of three all-Premier League ties.
