Bryan Mbeumo in action for Man United
And his performance against Aston Villa was the latest of his shocking displays.
The Red Devils managed to claw back from a two-goal deficit twice, but with no help from the Cameroonian forward.
His lack of influence was particularly concerning given the importance of the fixture, with United needing their attacking players to step up.
For a player who arrived with such high expectations, his recent performances are becoming increasingly difficult to defend.
And he has left his Man United manager with a decision to ponder over the international break.
Bryan Mbeumo's Aston Villa display exposes major Man United problem
Mbeumo was brought to Old Trafford to provide a consistent attacking threat, but his recent performances are raising serious questions about his role.
Carrick has been using him out of position as the number nine, and truthfully, it has been a failure of an experiment.
The United No.19 has not scored in his last five games, and is quickly becoming an issue up top.
As per FotMob, Mbeumo had the fewest touches of any starter, including Senne Lammens, who had 24 compared to his 21.
The Cameroonian is simply unable to get himself into the game when starting down the middle of the pitch.
The forward was also poor in his individual battles, with the African winning just 11 per cent of his total duels after competing in nine.
Elsewhere, he was also dribbled past more than anyone else during the fixture.
In fairness to Carrick, he does not have many top options for that role, with Benjamin Sesko out injured.
Nonetheless, he needs to find a solution to the issue that is quickly becoming Mbeumo.
What could Michael Carrick do in Man United's squad?
Whether Carrick will even be manager after the international break is another question that remains in the air.
However, if he is in the role, then he could look to use Matheus Cunha as an option through the middle.
Additionally, after Joshua Zirkzee scored against Aston Villa, the Englishman may put trust in the Dutchman to lead the line.
There are more options than just Mbeumo, and time out of that position, whether on the bench or out wide instead, needs to be put into consideration.
