Albion hit the woodwork five times and had a penalty controversial overturned as Graham Potter's men tasted defeat. Scroll down and click through to see how each Albion player rated.
1. Maty Ryan 6/10
The Aussie stopper conceded three but did little wrong for either. Rashford's effort was deflected and he could do nothing with Dunk's unfortunate own goal. Fernandes last gasp penalty was emphatic
2. Ben White 6/10
One excellent tackle on Martial to deny the United striker in the second half. Bamboozled by Rashford's brilliance for the second goal
3. Lewis Dunk 6/10
Harsh to get credited with an own goal for United's leveller. His fifth in the Premier League. Also so close to blocking Rashford's goal but it deflected beyond Maty Ryan
4. Adam Webster 7/10
Slotted in well on the left side of the defence this season. He hit the bar with a looping header on 30 minutes
