Oscar and Diego Costa each scored twice as Chelsea established a provisional five-point lead at the Premier League summit with a crushing 5-0 success at Swansea City on Saturday.
The one-sided victory, which saw Chelsea go 4-0 up inside the first 36 minutes, enabled Jose Mourinho’s side to pull clear of second-place Manchester City, who host Arsenal on Sunday.
Chelsea had lost two and won only one of their previous four away games, but they went ahead inside a minute at Swansea when Oscar drilled a shot into the bottom-left corner after Gylfi Sigurdsson conceded possession.
Eager to atone, Sigurdsson hit the crossbar within seconds of the restart, but Chelsea doubled their lead in the 20th minute when Cesc Fabregas teed up Costa to slot home.
Costa punished a mistake from Federico Fernandez to claim his 17th goal of the campaign in the 34th minute and two minutes later he teed up Oscar to finish with the inside of his right foot.
Andre Schuerrle added a late fifth from Branislav Ivanovic’s cross.
Southampton held on to third place with a 2-1 win at Newcastle thanks to a brace from new signing Eljero Elia.
Newcastle’s Yoan Gouffran scored a fortunate equaliser for the home side who rightly felt hard done by in the dying moments after claims for a penalty for a hand ball by Jose Fonte were turned down.
On-loan striker Radamel Falcao returned to the Manchester United starting XI at QPR after being dropped against Southampton, but spurned a good early chance to score when he was denied by a Rob Green double-save.
United manager Louis van Gaal persisted with a three-man defence and with the visitors toiling, their fans made their dissent plain at half-time by chanting: “4-4-2!”
Fellaini replaced Juan Mata at the interval before Van Gaal introduced 19-year-old striker Wilson for centre-back Jonny Evans, and within seconds United were in front.
Antonio Valencia motored to the byline on the right and cut the ball back for Fellaini, who took a touch before lashing a languid shot past Green from 12 yards. Wilson sealed victory in injury time, finishing at the second attempt after his initial shot was repelled by Green.

Christian Eriksen claimed an 88th-minute winner as Tottenham Hotspur closed to within two points of the top four by winning 2-1 at home to Sunderland, who gave striker Jermain Defoe a debut against his former club.

Improving Liverpool climbed to seventh place, four points below the Champions League places, after winning 2-0 at Aston Villa.
With Steven Gerrard rested, Liverpool took a 24th-minute lead when Fabio Borini slid in to convert Jordan Henderson’s delicate cross before Rickie Lambert added a second with 11 minutes to play.
Crystal Palace continue to benefit from the impact of new manager Alan Pardew, coming from two goals down to claim a stirring 3-2 win at fellow relegation contenders Burnley.
Efforts from Ben Mee and Danny Ings put Burnley 2-0 up after 16 minutes, but Palace drew level through goals from Dwight Gayle and Jason Puncheon before Gayle netted an 87th-minute winner.
