Portugal superstar Cristiano Ronaldo has expressed his disappointment by reportedly giving an ultimatum that it is either he who makes the exit from Real Madrid or current manager Rafael Benitez.

According to The Telegraph, the ex-Manchester United hotshot has reportedly said, "Either he [Benitez] goes, or I go [out of the club]," in the Los Blancos dressing room after the Whites were hammered by arch-rivals Barcelona 4-0 in the first El Clasico of the season on Saturday night.

Ronaldo looked a very frustrated figure during the match and the disappointment was clearly visible as Real kept conceding the goals, and Ronaldo, too, on a couple of occasions, could not get his headers past Barcelona custodian Claudio Bravo.

The Portugal skipper has made it known once again that he is unhappy with the Spanish giants. The 30-year-old forward looke like he is not taking in Benitez's plans. Ronaldo was nowhere near his best during the match against Barca.

The rumours of Ronaldo leaving Los Blancos have thus started once more, and United could once again turn out to be his possible destination. Red Devils manager Louis van Gaal has always admired the player, and the Dutchman gave a strong hint that Manchester United could re-sign the former favourite.

"Of course we would look [into possibly making a move to re-sign Ronaldo]," Van Gaal was quoted by Mirror. "He plays on the wings and he is fast and scores goals. I don't think there is a trainer in the world that doesn't like him.

"We are looking at all players, not just Ronaldo. But these players are mostly ungettable. With Ronaldo, let's wait and hope."

Real Madrid, after recording two straight defeats in the La Liga this season, have now slumped to the third spot in La Liga. Barcelona remain the league leaders, while Atletico Madrid are second, following their win at the weekend.
