Liverpool boss Jurgen Klopp was left furious with the behaviour of Manchester United's players during Sunday's 5-0 win at Old Trafford.

Klopp was left feeling frustrated after the game as he thought at least five of Ole Gunnar Solskjaer's men could have been sent off.

He felt that Fred deserved a red card for a head-high challenge on Naby Keita just moments before he was stretchered off the pitch following a red card tackle from Paul Pogba.

A source close to Klopp told the Athletic: "There could have been five red cards for United in total."

The source went on to speak about Fred's challenge on Keita, saying: "(Antoine) Griezmann got a red card for doing the same thing on Bobby (Firmino) in the previous game. Where's the consistency?"
