Arsenal manager Arsene Wenger has confirmed that midfielders Aaron Ramsey, Granit Xhaka and Alexis Sanchez will all feature in tonight's pre-season friendly game against Manchester City.
The Frenchman desperately needs to assess the fitness level of the players involved in the Euro 2016 Championship and Copa America.
He says he will be cautious with the 27-year-old's return who will certainly be a starter against Liverpool next week.
"Alexis [Sanchez] and Aaron Ramsey will play a part in the game," he told reporters.
"Both of them are in reasonably good form physically. I took this Friday and Sunday to give competition to everybody so I will see how much and how long I will play them for.
"Granit Xhaka will come in, certainly. He did not play at all on Friday, and maybe Calum Chambers too. We'll see in training. The players who have not played will all be involved on Sunday.
"The problem with Sanchez is to be cautious with him because it's nearly impossible. But you know what I did, I gave him a long break because I know that this was needed for him.
"They played two Copa Americas in a row and in England you don't have a winter break. He got an injury. I know as well that you give Sanchez five weeks holiday, he will stay quiet one week and after he will start to run everywhere, and he comes back fit.
"I hope I got it right, that he had a good rest and regenerated a little bit, because he looks alright. We will see on Sunday."
