Griezmann did little to answer his critics during his time on the pitch.

The fan said: "Joao, step on Griezmann, you have to injure him, it can't be that he starts before you"

Félix replied: "You should have more respect for Griezmann".

As expected, Felix defended his teammate before driving away.

Griezmann has had a less than satisfactory start in his return to the club but Diego Simeone is backing him to turn his fortunes around.

“They (the media) are making a movie and a morbid situation that clearly gives us the importance of having recovered an extraordinary footballer like him and that we can enjoy,” he said, per Sport.

“We hope that he gets better and can respond to the people that criticise him.

“He has a challenge to move forward and consequences for what happened in the past.”
