Pogba disobeyed Solskjaer: "Don't do anything stupid"

Liverpool were on fire on their last visit to Manchester. They scored five goals against Man Utd. After 50 minutes, Solskjaer's men were already 0-5 down. 

At half-time, the Norwegian decided to bring on Pogba as he thought the Frenchman could give something extra to the team. 

Before coming on, magazine 'GQ' reports that Solskjaer warned him. "Don't do anything stupid," he made it clear to him. However, it went in one ear and out the door. 

After 14 minutes, desperation got the better of Pogba and he was sent off for a very poor tackle on Keita. The Liverpool player had to leave on a stretcher. 

That was not the only thing. After the match, Pogba apologised to his teammates for having left his team with 10 men, but completely ignored Solskjaer.
