The Tottenham Hotspur boss has been discussing the north London side's faltering defence.
In other words, Tottenham's defence. And the Argentine says it's an issue that affects every one of his players.
You can't blame the goalkeeper, the full-back or the centre-back, he says, it's about finding a balance as a team.
Pochettino was speaking ahead of Sunday afternoon's trip to Burnley - one they must win if they are to stay in the hunt for a top-four place.
“This is our problem, we need to concede fewer chances and goals," the Tottenham head coach told reporters.
“But this is about the balance of the team, it is not about the keeper or the centre-back or the full-back or the holding midfielder. It is about providing the team with a better balance.”
Considering the widespread nature of Tottenham's defensive problems, Pochettino is a keen observer to notice the issue.
But what will he do about it? It is, after all, the Argentine's system that has created a number of flaws at the back this season.
As Pochettino says, the problem lies not with one player - the poor form of Kyle Walker, Federico Fazio, Jan Vertonghen, Eric Dier, Younes Kaboul, Vlad Chiriches and still frequent defensive mistakes of Danny Rose show that.
The system at some point breaks down, sometimes with not enough protection from midfield, sometimes from errors out wide. The Spurs boss has now publicly identified the problem: time to solve it.
