Jamie Redknapp is not renowned as Sky Sports' best pundit but that doesn't mean the former Tottenham and Liverpool star doesn't know how to stick it to Premier League managers when he fancies it.
He proved as much back in 2014 when he openly criticised Jose Mourinho after he responded sarcastically to Mike Dean's decision to award Sunderland what would prove to be a winning penalty.
Redknapp said on Sky Sports at the time: "What he's [Mourinho] just said is embarrassing. You're the manager of the team and you're trying to deflect it to the referee."
It didn't take long for Mourinho to respond. After Chelsea's 2-1 win over Liverpool at Anfield, he spoke to Geoff Shreeves and made it clear he was not impressed with Redknapp's comments.
In response to a basic question from Shreeves, Mourinho responded: "You speak with Jamie Redknapp and he tells you everything about it. It was about winning - you have your pundits and Jamie Redknapp, who is a brilliant football brain, they can explain to you everything."
Obviously, times have moved on. Chelsea went on to win the title that season only for Mourinho to get sacked seven months later. He is now manager of Manchester United while Redknapp is now better known for being a team captain on Sky 1's League of Their Own alongside Freddie Flintoff and Jack Whitehall.

And it is on that show that Redknapp was asked to recall the moment by host James Corden.
"As Sky Sports' sixth best pundit, have ever offended anyone with your analysis?"

Reminded of Mourinho's comments, Redknapp gave his opinion.
"I gave him a little bit of criticism … and obviously he didn't take it very well," laughs Redknapp. "That is a proper diva moment, isn't it?"
More on the original source of the controversy. In Mourinho's post-match interview following a 2-1 reverse against the Black Cats, he said "congratulations" to Dean for his "fantastic performance, really amazing performance".
He then said Mike Riley, the head of the referee's association "because of the way he organised the referees this season". Obviously, he was being sarcastic and was later charged by the Football Association for his comments.
