The Portuguese star was the catalyst behind his side's first win of the new La Liga season on Sunday but his lack of elation on the back of two landmark strikes was the main talking point after the game, a storyline he tried to explain after full time.

"I'm sad because of a professional issue and the club know why," he said.

"That's why I didn't celebrate the goals, because I'm not happy. The people [at the club] know why

"It's nothing to do with Iniesta [winning European player award]. I won't talk about this any more and I will concentrate on Portugal for now. There are more important things [than this]."

He added, cryptically: "The people at the club know about this. I can't say any more."
