Dean Henderson, Luke Shaw and Marcus Rashford were all disappointing in Manchester United's shock FA Cup fourth round defeat at home to Middlesbrough.

The Red Devils were expected to breeze past their Championship opponents on Friday evening, but another damaging outing unfolded at Old Trafford.

Jadon Sancho's goal looked set to send United on their way to victory but a controversial Matt Crooks equaliser took the game to extra-time and the visitors prevailed in a long penalty shootout.

There were three United players who stood out as the worst performers, of those to have played at least 45 minutes of action, and using statistical experts Sofascore we have looked at the men who may be fearing for their place under Ralf Rangnick.

Dean Henderson - 6.8/10

Henderson started between the sticks instead of David De Gea but he did his chances of keeping the Spaniard out permanently very few favours.

While the England international had little to do in the 120 minutes of normal time, five of his 12 long balls were still inaccurate and he played no key passes.

In the shootout, Henderson failed to get close to the penalties, barring one that squirmed under him in sloppy fashion.

Luke Shaw - 7.4/10

Shaw has dipped well below last season's high standards in 2021/22 and this was another disappointing night at the office for him.

The left-back lost possession a whopping 34 times in total, also losing six out of 14 of his ground duels.

Not only that, but Shaw also only managed to complete four out of nine crosses and long balls apiece, highlighting a sloppy outing from him.

Marcus Rashford - 6.3/10

It was Rashford who took home the lowest rating at Old Trafford, however, as his hugely below-par form continues.

The Englishman lost the ball on 11 occasions overall, missed one big chance and won only two out of eight ground duels, meaning he and Shaw combined to lose 55% of their individual battles on the ball.

Rashford also won no aerial duels and failed to make any defensive contribution, highlighting his lack of effective pressing from the front.
