The former Manchester United and Real Madrid star, who has scored a staggering 697 goals in 984 games during his career to date, told Juventus TV: "I have no secrets, just my dedication and my passion for this sport, I love to play football more than anything else.

"I've enjoyed myself in Portugal, England and Spain and I am now doing so in Italy. For me, it's a pleasure to score goals and to help my team win. I'm happy."

Juve are yet to lose in 27 league games to date this season, and the defeat in Madrid came amid a run of five successive domestic victories.

Having scored 22 goals against Atletico in 31 appearances for arch-rivals Real and converted the winning penalty in the 2016 Champions League final shoot-out, Ronaldo is confident the tie is still alive.

He said: "Everyone knows that they are a strong team, they defend very well, they don't take a lot of risks and they play on the counter-attack, but we are ready, and we will do everything we can to beat them."

Diego Simeone's men, who have won their last five games in all competitions, have made it to the last 16 for the fifth time in six seasons, and it is more than seven years since they have lost to an Italian club away from home.

But Simeone is adamant his side will take nothing for granted despite their commanding advantage from the first leg.

Simeone told a press conference: "They (Juventus) are a very strong team with top players in every position.

"We have to stay calm, be humble and know that we're playing a very strong side.

"These kinds of ties are divided in two halves, one at home and one away. We will try to take the match in the direction we want it to go."
