Lionel Messi's greatest trick? Barcelona icon stunned Iniesta and Busquets in 2016

Just imagine how much Paris Saint-Germain could charge for people just to watch Lionel Messi for a single training session.

If you think about all the miraculous things that Messi has pulled off in the heat of battle during incredibly tense games, then you can just imagine the extraterrestrial feats he’s executed when there’s no pressure or spectators.

Playing as a defender for Messi’s club must make for a miserable existence in training because a completely liberated version of the seven-time Ballon d’Or winner with the handbrake off must be absolutely nightmarish to face.

You only have to listen to Thierry Henry’s remarkable account of the carnage that Messi caused in Barcelona training during his prime, cutting up the entire team with mazy runs, to get the picture.

“In training, he wants to beat everybody,” Henry once explained. “You know, the typical one, where he gets fouled. But they don’t call the foul on him.

“Next thing you know, he will go and ask the keeper to give him the ball, and run past everyone and score. 

“He will take it from you, wherever you are, and score again. Until he gets a bit more relaxed. So then you end up losing the game. I’ve never seen that before.”

However, one of the most amazing things that Messi has ever pulled off in training – well, out of the clips that us, the public, have had the luxury of seeing at least – didn’t actually involve any of his teammates.

Rather, it actually came when Italian singer Eros Ramazzotti visited Barcelona’s training ground in 2016, messing around with Messi, Andres Iniesta, Sergio Busquets and Luis Enrique after they had presumably finished their session.

And halfway through the cordial keepy-ups, the celebrity guest gestures for Messi to try and score
