The two changing rooms

An hour before kick-off, both changing rooms were full and the tunnel was busy. When the referee walked onto the pitch, he had to whistle with his mouth. The clues no longer hand you everything on a plate.

Suspects

• Aníbal, the physio: He looks after the home team's legs and the away team's gossip.
• Belinda, the club doctor: She has the key to the medical room and the suspicion of someone who has seen it all.
• Carlos, the match delegate: He has to check both changing rooms before the match. He checked one of them very carefully.
• Delfina, the stadium attendant: She opens and closes every door. She says that day she didn't close any.
