Paul Pogba volleyed in the winning goal as Manchester United moved top of the Premier League by winning 1-0 at Burnley.
United only needed a point against Burnley to move above champions Liverpool ahead of the two teams' crunch clash at Anfield this weekend.
But the resurgent Pogba converted Marcus Rashford's cross with 19 minutes left to ensure United moved three points clear of their great rivals.
Burnley defended well but did not manage a single shot on target, while Ole Gunnar Solskjaer's side had a first-half goal Harry Maguire goal disallowed.
The hosts went close early on when Eric Bailly made a key block to divert Chris Wood's effort away from David de Gea's goal.
Anthony Martial fired off target when a presentable chance was given to him by Nemanja Matic before VAR took centre stage.
After a long review, Robbie Brady's foul on Edinson Cavani just outside the area was rescinded and Luke Shaw was booked for a foul on Johann Gudmundsson earlier in the move, with Burnley calling for a red.
Maguire impressively headed in a Shaw cross only for a foul to be awarded for his duel with Erik Pieters. Nick Pope then impressively kept out a Martial curler to ensure the first half ended goalless.
A golden opportunity went begging after the break when Cavani scuffed a close-range effort straight at Burnley keeper Pope after Martial had squared into his path.
Rashford had been enduring a quiet evening out on the right until he picked out Pogba at the edge of the penalty area just as it began to look like United would have to settle for a draw.
Pogba latched on to it and superbly volleyed in, with a deflection off Matthew Lowton ensuring Pope was powerless to keep it out.
There were a couple of late scares for United, with James Tarkowski squandering an opportunity and Maguire not penalised amid claims of handball, but they held on with only late injuries to Martial – who had a last-gasp shot saved by Pope - and Nemanja Matic dampening the mood.
