Arsenal manager Unai Emery says he will decide on Friday whether Mesut Ozil and Granit Xhaka will play against Liverpool on Saturday.
Ozil has not featured once since becoming the victim of an attempted carjacking last month, with illness also forcing him out of action last weekend against Burnley.
Xhaka also missed the match due to a leg injury, and Emery still hasn't decided whether they'll play at Anfield.
Speaking at a press conference, the Spaniard said: "Tomorrow is the last training and we are going to decide tomorrow.
"Today they trained, but really, I need tomorrow to have the last training, to be really sure how we can be better there. I know some players need to be fit and to improve 100 per cent to be in their best fitness.
"But tomorrow is the day. Really I am positive with some players for Saturday but I don't want to decide today or to say to you today how we are because tomorrow can change."
