Dimitri Payet forced through a return to Marseille
Supporters dubbed Payet a 'snake' and in the aftermath it emerged that Payet was upsetting team morale and separating himself from teammates in a concerted effort to force through the move, citing family reasons as the motive behind his desire to leave - as reported by The Sun.
The France midfielder later told L'Equipe that he actually left because Bilic played a 'negative' brand of football, he was 'bored' and felt the club was 'regressing'.
"The way we played, the defensive system we used, didn't please me," the France star told L'Equipe.
"You could say I was bored. I had had contact with Marseille and most notably with [Marseille coach] Rudi Garcia, who had a philosophy that I knew well.
"The choice was quick. If I waited six months I would lose six months."
Payet has five goals from 14 appearances since returning to his homeland.

But just over a year after professing his adoration for the West Ham fans and commitment to the club's long-term project, Payet has endorsed a sweary and self-indulgent video on Twitter which will have Hammers fans cringing.
The video shows Payet coming on as a sub on his return to L'OM set to the soundtrack I'm Coming Home by J.Cole ft. Skylar Grey which includes the words 'Back where I belong'.

The video was posted on Twitter by a Payet fan who referenced the night he made his comeback, commenting that he still gets chills from it, using a well known swearword for emphasis.
While Payet may have seen retweeting the video as harmless, it highlights the ego of the man who had divided the Hammers dressing room.
So here you go Hammers fans, that video in full, if you can stomach it.
