Arsenal boss Mikel Arteta admits he's worried about William Saliba's latest setback.
The France defender missed the draw with Aston Villa on Saturday due to a hamstring injury.
After the 2-2 result, Arteta said: "Tomorrow we will have more information. Tomorrow we will have another test on him and it will be more clear."
Asked if he was concerned about Saliba, Arteta added: "Yeah, for sure.
"Especially with the numbers that we have in the squad and looking at our bench. Very worried."
