Felix leading the charge for revenge against Ronaldo's Juventus

Young gun Joao Felix will lead the charge on Wednesday as his Atletico Madrid seek revenge on Juventus and their old enemy Cristiano Ronaldo in a potentially fiery Champions League opener.

Felix, touted as the heir to Ronaldo's throne, will make his debut in Europe's top competition when the when the Portuguese pair meet at the Wanda Metropolitano, with the La Liga outfit keen to shoot down the five-time Ballon d'Or winner.

Juventus dumped Atletico out of the competition last year as Ronaldo scored a sensational hat-trick that overturned a 2-0 first-leg deficit and put the Italian champions in the quarter finals.

The former Real Madrid man rounded off the evening by celebrating provocatively in front of the away fans at Juve's Allianz Stadium.

Now Felix is charged with bringing the old master down a peg or two.

The 19-year-old has been hailed as the new 'CR7' after his breakout season at Benfica last year, scoring 20 times as the two-time European champions won the Primeira Liga and reached the Europa League quarter finals.

Ronaldo's former manager at Madrid Jose Mourinho is convinced that Atletico bagged a "an incredible player" for a club record fee of 126 million euros ($142 million).

"I think he can cope. He seems to have a good personality," said Mourinho.

"He's in a good team, surrounded by experienced players, with a manager who knows what he wants. Probably Atletico is a good place for his development."
