Casemiro made a sensational double block to prevent goal, Man United fans call him the 'best CDM in the world'

Casemiro made a sensational double block to prevent a Barcelona goal, with Manchester United fans hailing his work ethic and calling him the 'best CDM in the world.'

The Brazilian starred as Man United beat Barca 2-1 (4-3 on aggregate) at Old Trafford on Thursday to book their spot in the next round of the Europa League.

Erik ten Hag's side fought back from a goal down to claim a big victory over the La Liga giants as they become one of the favourites to win the competition.

But it could have been very, very different had Barca taken a two-goal lead into the break.

With the score 1-0 to the visitors on the night, David De Gea made an error, which put Barca through on goal.

But Casemiro saved an almost certain goal as he made not but TWO phenomenal blocks.

He performed a great tackle to stop Sergi Roberto before blocking Franck Kessie's effort whilst lying on the ground.

Man United fans loved Casemiro's work rate to get back in a position to block Barca's attempts at goal.

One Twitter user wrote: "Can’t stop watching this.. please god give my man Casemiro everything he wishes for!!"

A second tweeted: "Amazing isn't he!!! As soon as DDG misplaced the ball, he knew it was danger. It was a big turning point."

A third added: "Casemiro saw the trajectory of the ball and reacted way before the player intercepted it. You can't teach that."

A fourth commented: "Cometh the hour, cometh the man! Honestly been the biggest transformation."

Another said: "A lot of modern day players would have just stood there and watched that unfold! Absolute commitment."

Of course, Man United produced a brilliant second-half display to win the game 2-1, with Fred and Antony scoring after the break.

Casemiro has been a revelation under Ten Hag since his move from Real Madrid last summer.

And former Man United star Robin van Persie highlighted the importance of the 31-year-old as well as Raphael Varane following the match

"Casemiro, Varane, these guys are winners and can get you through a tough moment in a game," he said.

"They have been showing it. Even though they were behind, I still felt they could come back in the game.

"That is the sign of a top team."
