Ronaldo suggested his time at Real Madrid could be at an end just moments after winning his fourth Champions League in five years with the Spanish giants.
Substitute Gareth Bale scored twice – including a brilliant overhead kick – as Madrid inflicted a 3-1 defeat on Liverpool at the Olimpiyskiy Stadium in Kiev.
But Ronaldo, who has now won five European Cups in all, has cast fresh doubts over his future following the match.
“I am going to enjoy this moment and in the next few days I will give an answer to the fans, who have always been at my side,” the 33-year-old told BeIN Sports Spain.
“It was very nice to be at Real Madrid. In the next few days I will speak. I am going to enjoy this with my team-mates and in the next few days I’ll give an answer.”
Ronaldo ended as the Champions League’s top scorer for a sixth straight season as Real became the first side in 42 years to win three consecutive European Cups.
“We made history. That’s the important thing,” he added. “The future of a player isn’t important.”
The final ended in tears for Liverpool’s Mohamed Salah, with the Egyptian forced off after half an hour with a suspected dislocated shoulder.
Out-of-form Karim Benzema was gifted an early second-half goal when he intercepted a Karius throw, poking the ball into the net – and although Sadio Mane quickly equalised, Bale struck twice.
The Wales international’s first goal was sublime and in many ways reminiscent of his manager Zinedine Zidane’s goal which won the 2002 final, but his second was comical as Karius let a 30-yard strike slip through his fingers.
