Cristiano Ronaldo has rejected accusations he said he is "sad" at Real Madrid to get more money from the club.Ronaldo, 27, refused to celebrate either of his goals in Sunday's 3-0 win against Granada and revealed his disquiet to reporters after the match.Several theories have been put forward to explain his mood, but Ronaldo denied his motives are financial."I am accused of wanting more money, but one day it will be shown that this is not the case," the forward said.Apart from the argument that the Portugal international is angling for a new contract, it has also been suggested that he was upset by a perceived lack of support from his club in his bid to be named World Player of the Year for a second time and because Barcelona midfelder Andres Iniesta was selected as Uefa's Best Player in Europe last week.Ronaldo has made a huge impact since joining Madrid from Manchester United for a world record £80m fee in 2009, and his 46 La Liga goals last season played a key role in helping Real becoming Spanish champions.He moved to ease fears from supporters that his performance level would decline by guaranteeing "that my motivation, dedication, commitment and desire to win all competitions will not be affected" by his feelings as he has "too much respect for myself and for Real Madrid to ever give less to the club than all I am capable of."Real team-mate and former Liverpool defender Alvaro Arbeloa offered his support to Ronaldo.He said: "If Cristiano is sad and needs the support of his team-mates then of course he is going to get it. And if it is the support of the fans, I am sure they will give it."In Real Madrid we are a family. When one member is not as happy as he should be we help him."When things are not right we all help."
