Arsenal are \"very worried\" about William Saliba\'s hamstring injury as he missed Saturday\'s draw to Aston Villa.
\"I think tomorrow we will have more information, we will have more tests on him and we will be more clear about it,\" Arteta said.
\"For sure [we are worried], especially with the numbers we have in the squad and looking at our bench. Very worried.\"
Arteta was forced to re-shuffle his defence with Jurriën Timber switching to the centre alongside Gabriel and midfielder Thomas Partey filling in as a makeshift right-back.
