Former Manchester United boss Jose Mourinho couldn't resist a little swipe at Luke Shaw at Old Trafford on Sunday.
The Portuguese manager was in the studio as a pundit for Sky Sports' coverage of Man Utd's 4-0 thrashing of Chelsea.
And he had a dig at Red Devils left-back Shaw, with whom he had a tricky relationship during his reign as United manager.
Mourinho was praising £80m signing Harry Maguire, who was named man of the match, when he dropped in the little jibe at Shaw.

"He (Maguire) fully deserved the man of the match," Mourinho said. "He was solid as a rock and as we know it's very important for a team to have that tactical knowledge, but also that personality and sense of reading the game.
"Harry Maguire has had to cover Luke Shaw, and he will learn this season that he will have to do this many times.
"He also had the confidence to play - he was fantastic."
Mourinho's relationship with Shaw had it's ups and downs at Old Trafford.
The left-back was frozen out at Manchester United and Mourinho called on him to "change his football brain".
Mourinho even questioned Shaw's weight and hauled him off at half-time in an FA Cup clash against Brighton.

But the pair reconciled and the 24-year-old earned his place in Mourinho's first-team, as well as a new contract at Old Trafford.
Manchester United thrashed Chelsea 4-0 in a thumping win to begin their Premier League season.
Marcus Rashford gave them the lead from the penalty spot during a close first-half in which Chelsea hit the woodwork twice.
But Ole Gunnar Solskjaer's men pulled away after half-time in devastating fashion on the counter-attack.
Anthony Martial doubled their lead after converting a low cross before Rashford added his second, taking in a delightful long ball from Paul Pogba before sliding it past Kepa.
