Arteta worried about Saliba twisted ankle

William Saliba was substituted in the 5th minute with an ankle injury

Mikel Arteta says that he is worried about the ankle injury that forced William Saliba off in Arsenal's 1-0 defeat to Liverpool.

Saliba was replaced in the 5th minute by Cristhian Mosquera and Arteta confirmed after the match that the France international had suffered a twisted ankle.

"He twisted his ankle during the warm-up, and he came in and he said he believed that he could carry on and play but he strayed away in the first two actions." Arteta said.

"I could see that he couldn't cope and we had to get him out, unfortunately. But thank God we have Mosquera, which we put in for the first time in the Premier League, his debut, not expecting it at Anfield and I think he was really, really good."

Then asked if he was worried about Saliba's injury, Arteta said: "I am because you cannot play a game of that stature. After you try, that means that there is something wrong."
