Saka came off during the game with a hamstring injury, while Arsenal lost the contest 2-1 away from home.
“No," he responded when asked if he regretted his choice to play Saka, who was not fully fit ahead of the game.
“It was a knock that he picked up the other day, and he was perfectly fine.
“It wasn't an action [injury], it was a backheel that can produce this type of injury. Let's see what the extent of it is, and afterwards, it was too late as well.
“[Saka's other worries] were more knocks than any other thing. The last few that he had, he hasn't really missed games.
“We gave him a break against Brentford in the Carabao Cup, and that was all."
