Ronaldo back in Real Madrid ready to tackle favourite victim Atletico

It will be a homecoming of sorts for the 34-year-old Ronaldo who lived a stone’s throw away from Atletico’s training centre.

Juventus signed Ronaldo because of his Champions League credentials.

No player owns as many Champions League titles as Ronaldo who has won five, four with Real Madrid and one with Manchester United.

He has scored a record 121 goals in the competition and of these 57 have proved decisive.

“We have to score at least one goal in Madrid, our qualification depends on this,” warned Allegri. “The two teams are evenly balanced.”

Ronaldo has played the lead role in all of his five previous European triumphs — from his towering header for United against Chelsea in 2008 to the tie-clinching, 97th-minute penalty against Juventus last season in the quarters.

He would also score twice against Juventus in the final.

It was to become the beneficiaries, rather than victims, of these match-winning moments, that Juve decided the only way to win the Champions League before Ronaldo retires is to have him on their team.

Juventus won the title in 1985 and 1996 but have finished runners-up five times since, including twice in the past four years.

– Hefty fine –

Ronaldo’s goal-scoring form has been undiminished despite recent controversies, including rape allegations made against him by an American woman which he vehemently denies.
