​Brazil and ​AC Milan legend Cafu believes that ​Juventus striker Cristiano Ronaldo will "suffer a little" in the Serie A following his sensational move from ​Real Madrid in the summer as the Italian league is a lot more difficult than the La Liga.

The 33-year-old initially struggled to find the net for his new club going three matches without a goal, but since then has been brilliant in front of goal, scoring three goals in seven appearances while also registering four assists for his teammates.

Cafu who spent 10-years in Italy with AS Roma and then AC Milan believes that the five-time Ballon d'Or winner will find it even more tougher in the Serie A and might struggle a little.

"He is going to give more visibility to Serie A. He will suffer a little in the Serie A because Serie A is a lot more difficult than La Liga in terms of the contrast in teams and in terms of the physical contact. But Ronaldo is always Cristiano Ronaldo. [He is the] best player in the world and will give a little more star power to Serie A," Cafu said as ​quoted by ESPN.

The 48-year-old who won two Serie A titles and one UEFA Champions League during his time in Italy, admitted that the league has seen a dip in form in the recent past, something which was very different in the past as all the great players wanted to play in Italy.

"We've had a much more competitive Serie A than now. In my adolescence, everyone would like to play in Italy. Roma, Milan, Lazio, Juventus, Sampdoria, Napoli. You had an obsession to play in the Italian Championship. Unfortunately, [now] it is less competitive than the Premier League, Bundesliga and La Liga. It has to return to the Serie A that we saw before," he concluded.
