Arsenal boss Mikel Arteta is hopeful Declan Rice is fine after victory over Crystal Palace.
Rice was substituted amid fears of a hamstring pull.
Arteta said afterwards: "He was feeling some tiredness.
"I don't know exactly what muscle it was but when he says that at 3-0 obviously we don't want to take any risks, and the same with big Gabi as well.
"He had some discomfort, he had a tackle in the first half and was a bit struggling so it was the right moment to take them off."
