Alexis Sanchez and Manchester United has certainly not been a good fit so far.
The signing of the Chilean in January was supposed to be the marquee acquisition that would help Jose Mourinho's side bridge the gap to Manchester City.
Sadly, the former Arsenal man has been more of a hindrance to United's progress since his arrival than the one accelerating it.
He's been in and out of the starting lineup and has struggled to find the back of the net when on the pitch.
Mourinho appears to have lost faith in him, with Sanchez benched for the Manchester derby on Sunday.
The Chilean did come off the bench in the second-half, but had virtually zero impact on the game.
It looks ever more likely that Sanchez will be leaving Old Trafford in January.
And judging by his behaviour in the dressing room after the defeat to City, United would be best getting him off their books.
According to The Sun, Sanchez "slammed his boots down in the changing room" and then openly criticised United's defensive tactics.
Whether Mourinho was within earshot is unconfirmed but if he was, that could be the end of Sanchez at United.
The boss will surely not stand for players undermining his tactics, especially one who has performed as badly as Sanchez has this season.
An inside source recently revealed that the Chilean is already looking for a fresh start.
They said: “He is totally fed up and at the end of his tether with Mourinho. He knows he can’t leave right now but is in talks with his agent about what they can do to try and sort the situation out.”
The only issue will be finding a club willing to take a gamble on a player hopelessly out of form and with huge wage demands.
