Real Madrid striker Cristiano Ronaldo has once again refused to close the door on a possible move from the club at some time in the future. Speaking two weeks ago, Ronaldo said that he would be delighted to sign a new contract with the club, but added that he would never say he would stay with the Spanish giants forever. Now he has confirmed those sentiments in an interview with Portuguese television channel TVI. \"I will never close the door on any club,\" he said, before sending a reassuring message to Real Madrid fans. \"If I do change then Barcelona will be a door that is a long way away. I am happy here and if I had to renew my contract with Real Madrid for the rest of my life, I would be happy to do so,\" insisted Ronaldo. The striker, who has scored four goals in two BBVA Primera Liga matches this campaign, spoke of the need for his club to win titles after three seasons totally dominated by FC Barcelona. \"A club such as Real Madrid cannot be a long time without winning a competition as important as the Champions League or the Spanish League. I am confident that things will change this season, we have started well,\" he added. Ronaldo also spoke about controversial coach Jose Mourinho, who has previously worked with Porto, Chelsea and Inter Milan. \"His success speaks for itself, he has won titles wherever he has worked. He is the best coach in the world and I want to win titles with him more than anything.\" \"If I have to choose a word to define him, it would be \'professional\' ,\" said Ronaldo.
