That’s the verdict of former Red Devils manager Jose Mourinho.
The two European heavyweights went toe-to-toe at Old Trafford on Wednesday in the first leg of their Champions League quarter-final tie.
Barca secured a 1-0 win thanks to Luke Shaw’s own goal on a rare occasion that Messi didn’t steal the show.
And he was unable to drop deep and control the game as he routinely does due to the energy and pressing of Scott McTominay.
The Scotland international was a favourite during Mourinho’s tenure and injuries saw him thrust into the starting line-up by Ole Gunnar Solskjaer.
And Mourinho was in awe of his performance.
The praise of McTominay comes amid news that:
“Because I think Scott McTominay in midfield he was like, but when I use this expression it’s obviously in the total positive sense of the word, he was a mad dog.
“Pressing higher and creating problems in Barcelona building up then really aggressive on the duels.”
McTominay repaid Solskjaer’s faith with his performance and the Norwegian couldn’t fault him after the game.
He said: “He’s developing every time he plays. He comes into training every day with a fantastic attitude.
“That is the way to improve. Every game he plays, he grows and grows. He was the first one to take the ball down and settle us.
“We had to slow the game down. We were too quick to give the ball away. The three midfielders did really well.”
