Atletico Madrid midfielder Arda Turan has vowed to cut his hair if the club overcome Real Madrid in the final of the Copa del Rey on Friday.
The Turkish international, who has recently sported a longer hairstyle, is expected to feature from the start against Atletico's capital rivals having recovered from injury.
"If we win the final, I'll cut my hair," he tweeted. "The game will be won over 90 or 120 minutes.
"Mentally and physically the team will need to be prepared. It will be a tough match, we will have to suffer.
"I'm happy, calm and prepared. The fans will drive us on from the stands. I think we're going to win."
Atletico have not won the Spanish Cup since 1996.
