Jose Mourinho hasn't ever really appeared totally happy with his squad at Manchester United and that hasn't changed this season.
The biggest clue over the summer was the constant stream of reports that Mourinho wanted a new centre-back to build his defence around and then the very apparent lack of a new centre-back arriving.
Not that his defensive problems are the only clue; another very clear issue the boss has is with his offensive options.
Alexis Sanchez was an incredibly high-profile January arrival but his impact has been a small fraction of what United hoped for when they beat Manchester City to his signature.
The Chilean has only started seven times this season but when he's failed to score in any of those games - his sole strike coming from the bench against Newcastle - you can hardly blame the United coach.
Mourinho has never been shy of letting it be known that he has a problem, and is usually happy to voice exactly what it is.
And he's done just that in an incredible interview - although neither Sanchez nor his defence were the target this time.
In an interview with Univision, as per Sports Witness, Mourinho spoke at depth about young players lacking character and he was happy to single out four of his own for having a problem.
“Maturity. When I say that, I mean maturity at a personal level," said Mourinho. "We [people of his age] are more men, we are more mature, we were more prepared to face life.
"We were less protected. In England, they call it ‘spoilt’. Today, we’re talking about ‘spoilt kids’. Our children are more ‘spoilt’ than we were.
“I think kids these days have a different social life than us, and players have around them an ‘entourage’, and I mean a personal entourage, the people that surround them, that protect them more, give them more affection, more excuses. They reach maturity more slowly.
“For example, this kid, Luke Shaw, who is currently the national team’s left-back, when I arrived here two years ago, he didn’t know how to compete. He had great potential, yes, but he didn’t know how to compete.
"We’re talking about Luke Shaw, [Anthony] Martial, [Jesse] Lingard, [Marcus] Rashford – young, big potential, but at the end of the day it results in the word I cannot say, but you use it a lot here… character, personality, they lack a little."
Mourinho hasn't held back there and has said exactly what he thinks about four of the biggest young talents at United.
It's difficult to argue with a man who works with them daily, of course, but to hang them out to dry like that - that's bold, but one that could see them rise to the challenge.
Mourinho simply has to be hoping for a reaction here, he just needs to hope it's a good one.
