Manchester United fell to yet another embarrassing defeat as Chris Wood and Jay Rodriguez struck to pile more pressure on Ole Gunnar Solskjaer who saw his side's top-four hopes dented.
This was Burnley's first win at Old Trafford since September 1962 and the victory could not have come at a better time for the Clarets. Sean Dyche's side were being dragged into a relegation fight until Sunday's win over Leicester gave them the confidence to land a devastating blow on another team with Champions League ambitions.
The spotlight inevitably falls on Solskjaer and the United board, and the Red Devils are in dire need of reinforcements and as the January transfer window comes to a close, they'll need to act quickly.
Here are the three things we learned as Manchester United lost 0-2 to Burnley at Old Trafford.
3. No Rashford, no goals
With Marcus Rashford ruled out with a stress fracture of his back, United needed Anthony Martial to step up in front of the goal. In two games without their talisman in attack, they have drawn a blank in both, missing chances that you feel he would have buried. Martial was bullied by the Burnley defenders and failed to create any impact on the game.
This only further reinforces the belief that the Red Devils need to sign a player or two during the January transfer window. The absence of Paul Pogba and Scott McTominay means that United have neither creativity nor steel in their midfield, but it is the absence of Rashford that looks like the biggest loss.
2. Burnley back with a bang
It looked like Sean Dyche's men were teetering on the edge of relegation, but the win at Old Trafford was another one of their typical performances. Rugged, resilient and dirty, the Clarets made themselves hard to play against. On Sunday, Dyche's men came from behind the shock Champions League-chasing Leicester.
And they have followed that up by claiming the club's first win on United soil for almost 58 years and their first victory over the Reds anywhere since 2009. There was an air of familiarity once Wood tucked in Burnley’s first goal and after Rodriguez scored the second, there was never any doubt what the final result would be.
1. End of the road for Ole?
Since Ole Gunnar Solskjaer's permanent appointment, United have won fewer league games than Burnley. The pressure continues to grow and the fans continue to get antsy. While the Reds remain in with a chance of breaking into the top four it is unlikely that they will bring in the club's fifth manager in less than seven years.
Solskjaer seems incapable of motivating United in these games were they are expected to roll over inferior opposition. A top-four place is there for the taking and United are still in the Europa League, FA Cup, and Carabao Cup. But the Red Devils desperately need reinforcements in the coming weeks.
