Arsenal boss Unai Emery has told Matteo Guendouzi 'don't change' after his dismissal in the Carabao Cup win over Blackpool.
Emery insists the youngster was unlucky to see red.
The manager said, "He is playing well and he is playing with one very important thing: good spirit. He is competitive. The action is one action. He plays this action, normally, he is pushing behind the player and the second yellow card…
"I don't know if it is experience, but he is playing with the spirit like I want today and in every match. We spoke in the dressing room at half-time. I said it is very important to keep control, but I don't think that he really lost control in this action.
"He played how the action demanded and the red card is one circumstance in the game."
Emery continued: "That is football. When you are playing, when you are on the pitch, you can have things positive or negative. Like an injury, a red card or 90 minutes of hard work. With the red card, it's like that. It's football.
"We have a lot of players looking to play and to take this responsibility to show their performance, their quality for the team and I am going to prepare with other players and thinking that we can also have a performance for a big match on Saturday."
