Form guide: United were just seconds away from sealing a comeback win over Fulham on Sunday when Darren Bent’s headed goal from close range ensured it was just one point rather than three for the frustrated Reds. But Arsenal’s trip to the north-west a day earlier ended in near-humiliation, with the Gunners four goals down at Anfield after just 20 minutes. Liverpool were 5-0 up early in the second half, but Mikel Arteta’s penalty reduced the arrears slightly.
Ins and outs: David Moyes may have the option of Marouane Fellaini after a two-month absence, but the Belgian suffered another injury setback leading up to the Fulham game. Forced out of action by a back problem and surgery on a troublesome wrist, the midfielder was sidelined by a slight groin problem in training last week and it remains to be seen whether he will be in the mix for Wednesday night. Jonny Evans (calf) and Phil Jones (concussion) were also not in the squad for Sunday’s match. Arsenal’s Aaron Ramsey is out for several more weeks with a thigh injury that has kept the Welsh international out of Arsene Wenger’s side since December.
Betting: The hosts are favourites with our official betting partners bwin, but it’s a close-run thing. Arsenal are 2.20 to win, the Reds are 3.30 while the draw is 3.40. More temptingly, Antonio Valencia is priced at 15.00 to score the opening goal in an away win, as he did in United’s last victory on the Gunners’ home turf in January 2012.
