Diego Simeone unsure of Jan Oblak return

Atletico Madrid boss Diego Simeone has admitted that he is unsure when summer signing Jan Oblak will be fit to return from a back injury.

The goalkeeper arrived at the Vicente Calderon from Benfica last month, but has struggled with a back injury since moving to the Spanish capital.

"[Oblak] is a question for the medical department," Simeone told Marca.

"Dr Villalon (Atletico's head of medical services) will surely inform us about it, and that's who he's working with."

A report has claimed that fellow summer signing Miguel Moya will start the season as Simeone's first-choice goalkeeper following a string of impressive pre-season performances.
