Atletico Madrid are expected to be without Arda Turan for their trip to Athletic Bilbao in the quarter-finals of the Copa del Rey this evening.

The capital outfit travel to San Mames with a 1-0 lead from the first leg, but will reportedly be without the Turkish international, who is struggling with a calf injury.

Boss Diego Simeone has also revealed that fellow midfielders Tiago and Joshua Guilavogui are also unavailable.

"Tiago and Guilavogui have not travelled," Simeone told reporters at a press conference.

Bilbao have not lost at San Mames this season.
