"After a year out and at 34 years old it's not easy," Milito said.
"But I am convinced that I can still offer this squad a lot and I will do my best until the end.

"I want to be fit and help the team. I'm going to do all I can for the shirt, then we'll see what happens.
"I am available on Saturday."
