For the fourth season running, Cristiano Ronaldo has been at a club where the manager has either left or been sacked.
If this had happened once or twice, you'd think it was merely a coincidence. But a pattern is starting to emerge and it could well be that Ronaldo is actually the problem.
The Portuguese star's match-winning abilities are well known. Even aged 36, Ronaldo has shown several times already at Manchester United that he can still bend a game to his will.

But does his superstar status and influence over a dressing room make it so much more difficult for a manager to do their job?
Is Ronaldo too sulky when he doesn't get his way, leading to friction with those trying to manage him?
We examine what happened with each of those four bosses and Ronaldo's role in their departure.
Massimiliano Allegri (Juventus)
Allegri's trophy-laden five year first spell with Juventus and Ronaldo's stint with the club only overlapped for one season.
On the surface of it, with Ronaldo scoring 28 goals during his first season in Italian football and winning the Scudetto, it seemed like a good match.
But by the end of that campaign, it boiled down to a simple ultimatum for the manager - either Ronaldo goes, or I do.
Earlier this year, Italian newspaper La Repubblica reported that Allegri sat down with Juventus chief Andrea Agnelli and encouraged the club to move Ronaldo on even after just one season.

Allegri believed his presence was stalling the growth of the team and blocking the pathway of young players to regular game time.
There was some truth to this - Ronaldo started 30 of the 32 Serie A matches he was fit and available for that season. He also started nine of Juve's 10 Champions League matches prior to being stunned by Ajax in the quarter-final.
As a £100million megastar signing, not only did Juventus fans want to see Ronaldo in action each week, the club's hierarchy would expect maximum returns from their expensive outlay on him.
Allegri felt in the long-term, Ronaldo's presence was damaging but Agnelli disagreed with him and it was the coach who had to hit the highway despite his consistent success.

It came after a year in which Ronaldo criticism of Allegri's tactics bubbled away beneath the surface. The Portuguese was reportedly not happy with a negative approach and some of the team selections.
One report suggested that Ronaldo had demanded a complete squad overhaul in the summer of 2019 so they didn't fail in the Champions League again.
But it wasn't an overhaul Allegri would oversee and when he returned to Juventus earlier this year for a second spell, Ronaldo didn't exactly hang around.

Maurizio Sarri (Juventus)
If Ronaldo thought his time at Juventus was about to get better following Allegri's departure, he was sorely mistaken. The friction between him and Maurizio Sarri was palpable from the outset.
There were suggestions that Ronaldo was less than impressed that Sarri, who'd just come from Chelsea, was even given the job.
In November, when Sarri hauled Ronaldo off for the second time in a week, the forward apparently shouted 'what the f***' at the manager before he stormed down the tunnel at the Allianz Stadium.
Afterwards, Sarri claimed that Ronaldo was suffering from a 'little knee problem' that was 'affecting his performances' but the player then trained for Portugal without any inhibitions.

They clashed over tactics, too. Although Sarri made clear Ronaldo would have a 'licence to be free on the pitch' it didn't work out that way.
Ronaldo didn't want to play as the lone frontman as Sarri hoped and wasn't shy in criticising tactics he felt didn't get the best out of him.
As at Chelsea, 'Sarri-ball' was disliked by fans and players and things reached a low point when they crashed out of the Champions League last-16 to Lyon despite two Ronaldo goals.
There was no way back for Sarri after that despite delivering another league title and he was sacked a day later. Ronaldo would not have been sorry to see him go.
