Cristian Tello photo leaves teammate exposed

Cristian Tello has posted an image on photo-sharing network Instagram that exposes a Barcelona colleague's bare bum.

The striker uploaded the seemingly innocent snap of him posing with teammate Pedro, who was clutching the match ball after scoring a hat-trick against Getafe at the weekend.

However, a naked figure can be seen stood behind to duo in the team's dressing room.

Defender Gerard Pique has speculated that the unwitting star of the photo could be fitness coach Aureli Altimira or trainer Pepe Costa.
