The deal was completed for a record fee of £19.5m. Ronaldo had an immediate impact in Serie A, scoring 25 League goals and featuring in every newspapers' front paper.
He was a true all-rounder, scoring free-kicks, making great runs and providing assists.
His first season at San Siro brought the UEFA Cup, with six goals in 11 games, including one in the final against Lazio, a 3-0 win in which he received the man of the match award.
Ronaldo went into the 1998 World Cup as the best player in the world, and helped Brazil reach the final, but a mysterious fit before the showpiece match saw him a shadow of his true self.
It didn’t seem to affect him long-term though, with the striker scoring 15 goals in 28 games over the following season.
That season was to be the start of a nightmare for Ronaldo as he suffered a ligament injury against Lecce. Following an operation, he returned to action in April’s Coppa Italia final, unfortunately, the reconstructed knee collapsed, and Ronaldo missed the whole of the following season. He played just eight games between the summers 1999 and 2001. This shows how much the injury affected Ronaldo physically and mentally - to play only 8 matches in 32 seasons of football. The Brazilian finally made a return to the pitch for the 2001-02 season, and four goals in Weeks 31, 32 and 33 had the Beneamata leading Serie A on the final day.
However, a dramatic collapse against Lazio saw the Nerazzurri defeated 4-2, Ronaldo weeping on the bench as another Scudetto slipped away. He never played for the Nerazzurri again, joining Real Madrid for €46m that summer after firing Brazil to glory at the World Cup.
