The Chilean has been on an extended summer break since following his exploits in this year’s Confederations Cup where the South Americans were defeated in the final by a German team with Shkodran Mustafi in the centre of its defence.
Both Alexis and Mustafi will begin their pre-seasons at the weekend, while their teammates take part in the Emirates Cup against Benfica and Sevilla.
“First of all you make a really good check up of where they are, how much they have worked during their break. After, once you know where you stand, they need an adjusted programme and to see how quickly you can fit them in again.
“Of course it depends as well on what is the need in the squad, what is their quality. All of these things together make your decision. Do you put them on the bench when they are not ready [to start]?
“It is easier to put a striker on the bench than a defender, sometimes. Because in a short period they can make an impact. We’ll see.”
