Jose Mourinho vs Paul Pogba - we've had confirmation that it's both happening and isn't happening.
Whatever the absolute truth, something is going on, as suggested by Pogba's comments after Manchester United's 2-1 victory over Leicester last week.
“You have to know one thing: a player that gets chosen and is happy, you always feel more comfortable than when he’s not happy - that’s all I say," said Pogba, before adding that “if you’re not happy, you cannot give your best” and, interestingly, that "there are things that I cannot say otherwise I will get fined."
The comments reignited a feud that was said to be in flow last season as Pogba struggled for form, even finding himself left out of the side.
A stunning World Cup performance that saw him finish as a world champion seemed to settle Pogba - as did being awarded the armband for the game against Leicester.
He rewarded that trust with the opening goal from the penalty spot - but his comments after really do suggest that all still isn't well.
And with things seemingly heading in the wrong direction, Alan Shearer has some advice that should be listened to.
Writing in a column for Coral, Shearer looked to Mourinho's past for how these things usually play out.
"There seems to be an on-going battle between Jose Mourinho and Paul Pogba at Manchester United and it does not appear to be going away," he wrote. "Most of the time in this situation, the players win the battle as Jose Mourinho knows as he has experience of this at Chelsea.
"If Jose does try to take on too many players at United, I would not be surprised if the same thing happens again.
"Conte came in at Chelsea with virtually the same team and won the league.
"Whether you like it or not, the players have all the power in the game now and inevitably they end up winning when there is an argument like this."
Shearer is, of course, referring to Mourinho's year with Chelsea after winning the title - he fell out with players and was gone before Christmas.
But that's not the only time that happened; Mourinho infamously divided the Real Madrid dressing room during his spell there and, much like he'd find with Chelsea later on, he was out the door a year after winning the title.
If this 'disagreement' with Pogba is to go away, the United boss could do himself a favour and make sure the bridges stay intact.
