Arthur Masuaku is surely on borrowed time at West Ham United under manager Manuel Pellegrini.
The DR Congo left-back has had a topsy turvy West Ham career.
After a disastrous start the former Olympiakos man was reimagined as a left winger under David Moyes.
His pace and skill were a threat and he started to endear himself to West Ham fans with his performances.
He got himself banned for spitting at an opponent during an FA Cup defeat to Wigan.
Hot and cold, but mostly cold
But his performances were a positive in helping West Ham stay up last season.
He is being used as a left-back again under Pellegrini this season, though, and has been nothing short of woeful.
Regularly at fault for goals and offering little going forward he has been in and out of the side.
Aaron Cresswell has also failed to shine, though, which saw Masuaku back in for the 4-0 drubbing against Manchester City last time out.
Masuaku defensive displays are scary
Once again Masuaku was at fault for at least two of the goals.
And when that was pointed out on social media the defender responded in rather childish fashion.
In doing so Masuaku inadvertently criticised Pellegrini for seemingly being the only person who doesn’t know his best position.
“Your life is useless imbecile everyone knows my real position,” Masuaku responded to a tweet criticising him.
A pathetic riposte if ever there was one.
Signed as a left-back, plays as a left-back, you’re a left-back
Masuaku was signed for no mean fee of £6.5 million as a left-back.
Even if he feels he is more adept as a winger he should have a basic knowledge of defending by virtue of playing there for his previous clubs and West Ham.
But time and again he fails when it matters most in the most difficult league in the world.
At this rate he is certain to be one of the first out of the door come January if West Ham can find a buyer.
Pellegrini has already been linked with a host of alternatives.
And he surely won’t be happy with Masuaku’s public response to a supporter even if he does plan on shipping him out come January.
