Cristiano Ronaldo has refused to confirm reports from Spain that he has agreed a new five-year deal with the club, as the striker's future at the Santiago Bernabeu remains uncertain.
Spanish newspaper Marca reported that the Portugal international had committed his future with Los Blancos until 2018, increasing his salary to 17million euros (£14.8million) per year after tax and negotiating a new arrangement over the sale of his image rights in the process.
However, when questioned about such claims, Ronaldo told reporters: "I'm not going to confirm anything - I'm just going to do my job like I always do.
"My future - I don't know. At this moment I'm a player of Madrid, the future, I really don't know.
"Let's see what's going to happen - but for the moment, I'm good where I am."
Former Real Madrid boss Jose Mourinho told ESPN recently that "the real Ronaldo" was the former Brazil, AC Milan, Real Madrid and Barcelona forward, with whom he worked during his period as a translator and assistant coach at Barcelona between 1996 and 1997.
The 28-year-old was also asked to comment on Mourinho's remarks.
"There are some things in life that don't deserve any mention. This is one of those things and I won't comment on it for obvious reasons. I always respect my coaches and try to learn from them," Ronaldo said.
"As we say in Portugal: 'I don't spit on the plate I eat on.' That's how I feel. I prefer to try and remember the positive side [to Mourinho]."
