Speaking about the jeers Real fans levelled on him during down times in the season, Ronaldo said: "It is not the moment to speak about [whistles]".
"If our current team is complemented with new players, we'll be really competitive in the Champions League next year".
- became the first team to successfully defend the title since AC Milan in 1990.
"But Real Madrid have important players and when they have a player (Ronaldo) who wins the Ballon d'Or it's a huge advantage".
The Frenchman recalled previous criticism when he said: "I don't want to say I'm very good because before I was scandalously bad as a coach and now I'm supposed to be the best".
"It was a very special occasion for me personally and it was an incredible feeling to lift that trophy here".
- became the first player to score in three finals in the Champions League era, adding to his strikes in the 2008 and 2014 showpieces.More news: Cristiano Ronaldo brace guides Real Madrid to Champions League victory

"Zidane believes in us a lot", Ronaldo said. They nearly went ahead on six minutes as Miralem Pjanic's 20-yard effort brought an excellent flying save from Madrid goalkeeper Keylor Navas.
One of the first things Navas' counterpart, Gianluigi Buffon, had to do was pick the ball out of his net. Few midfield trios can compete with Luka Modrić, Toni Kroos and Casemiro. It was a typically razor sharp break from Zidane's side with Karim Benzema feeding Ronaldo, who played a one-two with Dani Carvajal before sweeping a 15-yard shot inside the far post.
Ronaldo's effort was eclipsed seven minutes later by one of the all-time great final goals.
Mandzukic also scored the last time the final was held in Britain, when Bayern Munich beat Barcelona in 2013. But the magnificence evoked memories of another showpiece staged in the United Kingdom when Zidane volleyed into the top corner in Glasgow to help Madrid beat Bayer Leverkusen.
Thousands of football fans were watching a live relay of Juventus' Champions League final against Real Madrid in Cardiff when a bang was heard and rumours of an explosion spread.
"I'm not going to say that I'll be here for the rest of my life, that's doesn't exist", Zidane said.
It owed much to Madrid controlling midfield, largely thanks to Modric, who set up Ronaldo's second.
"You need a guy to score the goals and he did it again", said the Germany global.
