He recounted witnessing Messi berate himself for errors made on the pitch, even to the point of swearing and tugging at his own shirt in frustration, before making an immediate amends when he took to the field again.

Bartra recalled Messi's reaction after missing a penalty, saying: "He has had bad moments on a football field. I've seen him in a dressing room swearing at himself and pulling his shirt for missing a penalty. I heard him saying, 'What have I done?'

"Then he would come out in the second half and be the best, dominating the field. That's what made him the best. Beyond technique, it's about getting up again.

"It is about knowing what to do with what happens to you, what solution you bring to what you encounter. Not playing the victim, but taking it with responsibility."

The Venezuelan, who briefly shared a changing room with Messi in Florida before moving to CF Montreal, was taken aback by the Argentine superstar's down-to-earth nature and meticulous habits.

"Not even God is as well-known as he is. Seeing him sitting there was something impressive: folding his shirt, matching his uniform with his watch, and shoes with his shirt.

"He would sit down, and you'd say: 'Wow!' He'd greet you normally. That, despite being a guy who has won everything, he always arrived first for training."

Martinez continued, adding that Messi raised the standards of everyone in his squad, as he claimed: "He was great with us, he was great with me. And you felt you had to be at his same level."
