Chelsea are also still in the hunt, but nearly threw away a four-goal lead at home to Bolton Wanderers, while Arsenal rallied to beat Wigan Athletic.

Alan Shearer gained his first point as Newcastle United manager, but his side remain in the relegation zone after a 1-1 draw at Stoke City.

Middlesbrough are not yet dead and buried after Gareth Southgate's side recorded a rare Premier League win over fellow strugglers Hull City.

West Bromwich Albion let a lead slip in drawing at Portsmouth, and Tottenham Hotspur closed on West Ham United in the race for a Europa League place.

Fresh from scoring an injury-time winner a week ago, Italian teenager Macheda was once again United's saviour as the leaders won 2-1 at spirited Sunderland.

Macheda climbed off the bench to turn home the winner with his first touch on 76 minutes to claim a priceless three points.

Nemanja Vidic almost provided United with the lead on 17 minutes, but the Serbian defender's header was cleared off the line by the covering Danny Collins.

United did make the breakthrough two minutes later when Wayne Rooney, playing on the left of midfield, clipped in a perfect cross which Paul Scholes glanced into the far corner.

Sunderland responded positively and almost levelled before half-time when Carlos Edwards' low cross was deflected on to his own post by Jonny Evans.

The Black Cats deservedly equalised 10 minutes into the second half when Kenwyne Jones stabbed home from close range after an initial poor header from Teemu Tainio's cross.

Sir Alex Ferguson threw on Macheda and got an immediate reward when the striker diverted Michael Carrick's wayward effort past Craig Gordon to deflate a Sunderland side who deserved a point.

Fernando Torres was in deadly form as Liverpool continued to boost their goal difference with an emphatic 4-0 victory over a limp Blackburn side at Anfield.

With Steven Gerrard starting on the bench, it was left to Torres to inspire the title chasers and he opened the scoring after just five minutes with a stunning volley after chesting Jamie Carragher's searching pass under control.

Rovers keeper Paul Robinson denied Javier Mascherano and Dirk Kuyt with smart stops, as Torres and Yossi Benayoun produced glaring misses from the rebound on each occasion.

Torres, though, did take advantage of slack defending to increase the lead on 33 minutes as he darted across the box to powerfully head home a free-kick from fellow Spaniard, Xabi Alonso.

Liverpool cruised through the second half against a Blackburn side devoid of an attacking threat, with centre-half Chris Samba pressed into action as a striker.

Daniel Agger smashed home a left-footed shot seven minutes from time before substitute David N'gog completed the scoring in injury-time as he nodded home from close range.
