The Turkish attacker is confident that los Colchoneros can beat Real Madrid in Friday's final while Tiago Mendes is hoping to cap an excellent season for the club
The capital club face their city rivals as they look to win the competition for the first time since 1996 and the Turkish schemer is ready for the task ahead.
"If we win the final, I'll cut my hair," he said in a Q&A session with fans on Twitter.
"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."
Meanwhile, Atleti midfielder Tiago Mendes says his side must be prepared to face an excellent team if they are to reward their efforts throughout the season.
"It will be difficult because Real Madrid have great players," the Portuguese told the club's official website.
"It is an important match because it is a final, we’re playing for a title against Real Madrid and it is very important because after this amazing season we've had we can round it with a title at the Bernabeu."
Atletico have not beaten Real Madrid for 14 years.
