Real Madrid midfielder Casemiro has revealed he had already made a bet with Cristiano Ronaldo that the superstar forward will stay with the European champions.
The 33-year-old hinted at a shock exit from the Spanish giants, despite being contracted until 2021.
But Casemiro said he was so confident Ronaldo would stay, he had already made a bet with his team-mate.
"I've already bet with him. I bet he stays," the Brazil international said.
Gareth Bale was Madrid's hero in Kiev, the Wales star scoring a brace after Sadio Mane had cancelled out Karim Benzema's opener.
The 28-year-old also suggested he could leave in search of more game time, while Madrid are linked with numerous players this close-season – including Neymar.
Casemiro said he would welcome any strong additions to the squad, but he wants more of the same from Ronaldo.
"Of course, every year people talk about who arrives and who leaves. No doubt players like Neymar, [Eden] Hazard and [Robert] Lewandowski have lots of quality," he said.
"They are always welcome here because they have a lot of quality, but what I want from Cristiano is what he has been doing.
"And in the ends in the finals, it's always the same."
He is not the first Real Madrid star to back Ronaldo to stay at the club. Karim Benzema, who netted the opener in Saturday's final, does not believe the Ballon d'Or winner will depart, while president Florentino Perez also cast doubt on the prospect of the Portuguese departing this summer.
