The 33-year-old has been backed to bring the Champions League trophy to Turin but the former Inter star believes it will be a difficult quest
The presence of Cristiano Ronaldo may help Juventus close the gap on the top teams in Europe, but it is no guarantee that they will win the Champions League, Lothar Matthaus has said.
Ronaldo, 33, led Madrid to the Champions League title last year to win the fourth winners' medal of his career before leaving the Spanish capital for Juve.
The Portuguese attacker has been tipped to fire the Turin side to continental success, who have reached the final of the European competition twice in the last four years but lost to Barcelona and then a Ronaldo-led Real Madrid.
