Ronaldo refused to celebrate after scoring twice for Jose Mourinho’s side in their victory over Granada last Sunday, citing a dispute within the club as the reason.
But the ex-Manchester United goal machine, 27, did celebrate his equaliser in Portugal’s 2-1 win against Luxembourg on Friday.
And Old Trafford winger Nani said: “Ronaldo’s fine. Haven’t you seen him? He’s not sad, he’s fine.”
