AC Milan legend Zvonimir Boban believes Juventus can win the Champions League this season.
The Bianconeri have won Serie A for the past seven seasons in a row, but haven't won the Champions League since 1996.
“I think the sporting aspect was the biggest part of the deal," Boban said at the Globe Soccer event in Dubai.
“Ronaldo is Ronaldo, if after that he also brings marketing appeal then that's just an extra.
“I think given what they've shown they're the favourites [for the Champions League], then we have to see how they'll play against the very big teams.
“Obviously with Ronaldo the team is better than last year. It's difficult to put a figure on it, but he certainly makes them 15 per cent stronger.
“He always scores, he's incredibly consistent and has the knack of being in the right place at the right time.
“I expected him to adapt to Italian football, because it's not what it was in the 80s and 90s."
