thumpings at Arsenal and Spurs with wins over Chelsea and Sunderland respectively. Martinez returned in the summer to the club he graced for four seasons as a midfielder in the '90s. The Spaniard began his managerial career with Swansea in 2006/07 and, in his first full season, guided them to the League One title. After the Swans just missed out on a Championship play-off place the following term, Wigan came knocking.
Referee: United's opening-day 1-0 win over Birmingham was the first time Lee Mason has taken charge of a game involving the Reds. The Lancashire official has presided over 10 other Premier League matches this season, including Wigan's 2-1 win at Burnley in October, issuing a total of 29 yellow cards and four reds.
Rivals watch: On Tuesday night, high-flying Aston Villa welcome Liverpool and Bolton travel to Hull. The only other game on Wednesday night is third-placed Arsenal's trip to rock-bottom Portsmouth.
