#2 Inconsistency
Not many United fans might agree to this, given their affection for Martial but the player has been heavily inconsistent since arriving in England.
In his 86 league appearances, he has netted 24 goals and provided for another 15. A valid argument can be made over his playing time, but the player has had sufficient chances to deliver.
When the team needs him the most, the Frenchman fails to make an impact. Even when Jose trusted him with a string of starts in late October 2017, Martial barely contributed to the game.
There are days when the player appears to be sensational but such a seasonal player cannot be a guaranteed starter at Manchester United.
On top of that, his agent is keen to get his client a new club only because he is being asked to fight for a spot in the starting XI of one of the biggest clubs in football.
