Ronaldo refused to celebrate either of his two goals in Real's 3-0 victory over Granada on Sunday, later attributing his muted reaction to being 'sad' because of a 'professional issue' at the club.

The reaction sparked rumours of a possible departure from the Bernabeu for the Portuguese star, but Perez has played down the matter.

"If he wanted to leave he'd have said so when the transfer window was still open," the 65 year-old told Marca

"There are other reasons behind it."

Ronaldo himself took to Twitter to dispel rumours that his dismay was due to a desire for a new contract.

"That I am feeling sad and have expressed this sadness has created a huge stir," he wrote on the social networking site.

"I am accused of wanting more money, but one day it will be shown that this is not the case."
