Man Utd fans furious after shocking tackle on Casemiro during opening pre-season friendly

Manchester United fans are furious after Casemiro was the victim of a shocking tackle in a pre-season friendly against Rosenborg.

United begun their pre-season schedule at Rosenborg on Monday, with Erik ten Hag fielding a young team to take on the Norwegian side.

Amid an XI of youngsters, Marcus Rashford, Mason Mount and Casemiro all featured from the start against the Norwegian side, with the latter the subject of a horror challenge in the first half.

Tomas Nemcik lunged for a loose ball, only to miss and connect with Casemiro's shin.

While the Brazil international was able to continue after receiving treatment, Nemcik was lucky only to be brandished a yellow card.

Fans on social media were furious at the challenge on the midfielder.

Writing on X, one person said: "Some of the tackle on our lads are horrendous. Casemiro lucky not be injured. Mount has also been given some rough tackles."

A second said: "I know it's a friendly, but that was a red card! Awful tackle! Genuinely could have been a leg breaker."

A third wrote: "Someone needs to absolutely take out that Nemcik lad for Rosenborg. Nearly broke Casemiro's leg and completely cleaned Hannibal out of it. "

A fourth added: "Nemcik for Rosenborg with an absolutely disgraceful tackle on Casemiro. Friendly or not, that’s a red card. Disgusting."

A fifth person said: "For a pre-season game, that is a diabolical challenge on Casemiro. Nemcik gets away with a yellow because of the circumstances..."

A sixth said: "Nemcik horrible challenge on Casemiro.. would have been a redcard if not a friendly... sees a yellow instead."

Ten Hag will be hoping for a big improvement from his side this term. The Dutchman was handed a new contract after winning the FA Cup, but few would have considered last season's performances as convincing.
