The Spaniard played with Ronaldo for one season at Camp Nou, where the Brazilian gained the attention of the watching world by scoring 47 goals across the 1996-97 campaign, before he moved to Italy to join Inter Milan.
Ronaldo became a household name in football from the late 1990s to mid-2000s and is considered as one of the best footballers of all-time despite a series of severe knee injuries which curtailed his promising career.
Oscar has hailed the talent of the legendary striker and insists he had seen nothing like the former Inter Milan man until Messi arrived.
The retired Spanish footballer told Marca of his experiences alongside the two World Cup winner: "I was lucky to be very close to him for some of his goals, I saw how fast he was moving, it was even difficult to catch him to celebrate goals, he was still at the same speed.”
"From his very first training sessions we saw that he was a different player and that he was going to help us a lot.”
"You just knew he was going to be a world star, and he was, but what caught my attention most was his humility, he treated everyone the same and was always smiling and joking, he gained confidence very quickly."
He added: "Until the arrival of Messi, I hadn't seen a player who drove with the ball at that speed.
"I have only seen him and Messi do that.”
"I have been fortunate to have many great team-mates, but without a doubt Ronaldo is in the top three."
