Jose Mourinho opted to use the word betrayed before he was dismissed as manager of Chelsea. Following defeat at the King Power Stadium, the Portuguese tactician claimed that his work had been betrayed.
Considering his side secured the Premier League title with ease just months before, it wasn't exactly surprising that he felt let down by his so called stars.
But which players have really let their managers down this season?

In all honesty, we could name the majority of Chelsea stars - excluding the much-loved Willian, of course - but we've added a couple of other names just to mix things up.
Here are five of the biggest stars to have let their managers down this season...

Ah, Diego, what has happened? The 2014 summer signing from Atletico Madrid was outstanding last season as he scored a hatful of goals to help the Blues secure the title.
This season, however, he has been nowhere near the required level; he has been sluggish throughout and hasn't been able to get back to full fitness.
We're all well aware that he returned to Stamford Bridge unfit after the summer break and it certainly cost Jose Mourinho. Last season's heroics of 20 goals from 26 games were superb, but three strikes from 14 league outings this term make pretty grim reading.
Manchester United captain Wayne Rooney just hasn't led from the front this season. Of course, Louis van Gaal has come under growing pressure at Old Trafford, but he could have done with a couple of inspirational performances from his skipper. That just hasn't transpired.
Instead, Rooney has looked way off the pace; two goals in 13 league games just isn't good enough for a man who was once so lethal in front of goal.
Is age catching up with him? He's played at the top level for so long now and no longer appears to be the same powerful forward that he once was. Surely, though, he could have given more...
Van Gaal has stuck by him, but Rooney just hasn't performed for his manager.
It wasn't long ago that Eden Hazard was placed in a bracket just behind the likes of Lionel Messi and Cristiano Ronaldo. That is no longer the case.
The Belgium international has had an opening half of the season to forget. Without a goal and just two assists in the Premier League, Hazard has been a mere shadow of his former self.
He's no longer running at players like he was last season and appears to lack the desire to succeed in west London. In truth, his dire form has come from nowhere, but it will be interesting to see if he can turn his season around under the guidance of Guus Hiddink.
Stay with us here. Raheem Sterling certainly hasn't let Manuel Pellegrini down, but he most definitely let Brendan Rodgers down. It really could have been different if Sterling had stayed on Merseyside.
Naturally, it was always going to take time for Liverpool's new boys to adapt to the division, but they didn't do it in enough time to save Rodgers from the sack.
Sterling would have contributed in terms of goals and assists and who knows where Liverpool and Rodgers would be if they still had him on board.
From the best and most consistent right-back in the division to a huge liability. Ivanovic's decline came at the worst possible time for Mourinho.
Ironically, the towering defender netted his first Premier League goal of the season in the post-Mourinho era on Saturday, but he's really had a tough time of it recently. In truth, the writing was on the wall right from the off after Jefferson Montero gave him a roasting on the opening day of the campaign.
At 31-years-old, Ivanovic has it all to do in pursuit of redemption at Stamford Bridge.
Who are we missing? We know Cesc Fabregas and Memphis Depay are lucky to avoid this list, but let us know your thoughts in the comments section...
