Manchester United suffered a humiliating defeat at home to Bournemouth in the Premier League on Sunday, and it could spell the end of Michael Carrick at Old Trafford.

Carrick made the huge decision to drop Bruno Fernandes to the bench after he questioned United's tactics during the week, and it's a decision that didn't pay off.

Carrick even opted to keep Fernandes on the bench without bringing him on, despite the Red Devils struggling going forward.

Although Carrick has to take a large portion of the blame for the defeat and their recent performances, he was let down by a number of players against Bournemouth.

In fact, you could argue that a number of them have even potentially cost him his job, with the pressure mounting on the United manager.

Here is how the players performed on our report card.

Man Utd players let down Carrick

Senne Lammens - C

Couldn’t do an awful lot about the opening two Bournemouth goals, but looked sloppy with the ball at his feet. Often putting his team-mates under pressure in unnecessary situations.

The United goalkeeper was, however, in no-man's-land for Bournemouth’s third of the game, coming out of his box to be beaten by Evanilson.

Leny Yoro - D

A huge mistake when slipping to give Bournemouth the chance to make it 2-0. Slightly unlucky, but didn’t look comfortable throughout the game at all.

Clearly not suited to a right-back role, and that’s on Carrick.

Harry Maguire - C

Harry Maguire is meant to be the leader and experience at the back, but the defence do not look organised whatsoever.

Carrick needs more from him to help get the best out of others, but the whole defence looks lost at the moment. Certainly some debate as to whether he should have left the ball for Lammens or not for Bournemouth’s third goal.

Ayden Heaven - D

A nightmare afternoon for the young defender. Constantly giving the ball away and struggling to deal with Bournemouth’s third-man runners.

Clearly not ready to be playing week in week out in the Premier League.

Diogo Dalot - B -

Showed some promise when getting forward down the left-hand side, but final delivery left a lot to be desired.

Left a lot of space for Bournemouth to attack in transition, leaving United exposed at times.

Carlos Baleba - C

Not Carlos Baleba’s finest display. Had looked like he was going to help solve United’s midfield issues in recent weeks, but Bournemouth found it too easy to play through the middle. He’d often vacate his position to go and get the ball, leaving United exposed.

Andrey Santos - B -

Was more involved for United than any other player, trying to make things happen from deep. He didn’t make an awful lot happen, but at least he was trying to progress the ball and was putting himself about.

Amad Diallo - C

Showed little to no threat on the right-hand side. Created very little and didn’t give Adrien Truffert a difficult afternoon.

Need to start seeing more from the United winger when he is given an opportunity.

Youri Tielemans nightmare performance

Youri Tielemans - E

A shocking performance from Youri Tielemans. Was so weak in duels and offered nothing in possession. Shouldn’t be a starter in this team at the moment.

Consistently letting Carrick down. Rightly hooked at half-time. His performances might have cost Carrick his job, but the United boss does keep picking him.

Mason Mount - B -

A difficult and unfamiliar role for Mount in this game in the first half. Was brought in more centrally in the second half, but couldn’t put his stamp on the game.

Still, one of United’s better players and was trying to be positive.

Bryan Mbeumo - C

Had very little service in the opposition penalty area. The lack of creativity was a real worry for United.

Wasn’t an awful performance from him individually, but did offer nothing in attack, mostly through little fault of his own.

The likes of Heaven, Yoro, and Tielemans may have just cost Carrick his job, as the United manager is going to struggle to recover from this.

It remains to be seen whether Carrick is going to remain at Old Trafford, but after the big decision to drop Fernandes and then to lose, it's not looking good for the manager.
