The Portuguese attacker returns to Old Trafford on Tuesday night for the first time since his €93 million move to the Santiago Bernabeu, and the Argentine has hinted his belief that their rivalry which has developed since his arrival in La Liga was foreseeable.
He told Optimum Style: "Even before he [Ronaldo] signed for Madrid, I knew he would be my great rival in the following years."
The Argentine is fed up with rumours being created about him, as he is often the focus of media attention due to his moniker of being the best player on the planet thanks to four consecutive Ballon d'Or awards.
"Most things that have been said about me are invented. I'm a normal guy and I just want people to judge me as a player," he added.
"There is nothing nicer than to score and to win. I play with many good players and it would be wrong to mention just one."
