High-flying Hull City look to spring another shock, this time on the champions' patch...
Form Guide: United unexpectedly dropped two points at Everton last weekend, but bounced back with a routine home win over West Ham on Wednesday. Despite the Goodison slip, the Reds are still 10 games unbeaten. Hull's run of four straight wins was ended by a comprehensive home defeat by Chelsea on Wednesday, but the Tigers remain two points ahead of United in the Premier League table.
Ins and Outs: Michael Carrick returned from injury as a substitute against West Ham, and could be pushing for a place in the starting line-up. Fellow midfielders Owen Hargreaves and Paul Scholes are still out. Hull have no new injury concerns after their humbling by Chelsea, but will definitely be without broken leg victim Craig Fagan.
Star Man: Geovanni's arrival from Manchester City has proved a masterstroke by Tigers boss Phil Brown. The Brazilian is afforded a free role in Hull's attack, a move which has yielded four goals so far this season. Reds beware, his winning strikes at Arsenal and Tottenham suggest a taste for the big occasion. And, of course, it was Geovanni who scored the winner in the August 2007 Manchester derby.
What are the odds? United: 2/11 Hull: 14/1 Draw: 11/2 (manutd.com/bet).
Rivals Watch: Chelsea v Sunderland (Sat 15:00), Stoke v Arsenal (Sat 15:00), Tottenham v Liverpool (Sat 17:30).
