However, players from both teams squared up after a “naughty incident” on 24 minutes.

Alejandro Garnacho was attempting to get past Bayern’s Kingsley Coman when he ended up knocking him heavily into the pitchside hoardings.

The pair got in a tangle before the Man Utd player accidentally ending up throwing his Bayern counterpart into the boards.

The teammates of the French player hurried to confront Garnacho, who quickly received support from his own teammates.

Luckily, Coman was unharmed by the altercation because the referee intervened and allowed the game to continue without being stopped.

However, not everyone shared the official’s conviction that nothing nefarious had happened.

Ex-Chelsea and Blackburn striker Chris Sutton told BBC Radio 5 Live: “I think Garnacho is a bit naughty there.”

And it seems that some viewers tuning in also thought the same.

One fan wrote on social media: “Clear foul by Garnacho on Coman but not given.”

Another said: “Big fan of Garnacho hurling Coman into the advertising hoardings like something out of WWE.”

A third added: “Garnacho could’ve really hurt Coman! But not even a card.”

While another said: “Garnacho just chucking Coman into the advertising boards, you know that didn’t feel good.”
