Portugal coach Fernando Santos hailed Cristiano Ronaldo who won a second-half penalty and converted it himself to open the scoring against Ghana in their 3-2 victory.
"I think Cristiano is a phenomenon, a legend," Santos said. "In 50 years time, we will still be talking about him."
Ronaldo was substituted in the 88th minute to a rousing reception around Stadium 974 in Doha at the start of what is likely to be his last World Cup.
Santos rebuffed suggestions by his Ghanaian opposite number Otto Addo that the penalty decision was incorrect - given for a shove by defender Mohammed Salisu - and should have been reviewed by US referee Ismail Elfath via the Var system.
"If the Var tells the referee that he has to have a look, he will have a look," he said. "If the Var didn't call over the referee it's because they watched the images and there was nothing to see."

Who are the star names?
Cristiano Ronaldo will almost certainly be taking part in his last World Cup. The all-time leading international goalscorer will look to add the World Cup to his horde of trophies. Ronaldo took the official player of the match award in the opening win against Ghana, but Rafael Leão was the top-rated player by Telegraph Sport readers, scoring a rating of 8.3.
Bruno Fernandes will also be one to watch, as will Rafael Leao, who has been impressing at AC Milan this season.
