The Euro 2016 winner however appears to be low in terms of his confidence and was taken off at half –time during the clubs last two Premier League fixtures against Chelsea and Bournemouth.
Swans manager Paul Clement is however backing the player to overcome his current situation.
He said: "Renato is struggling for confidence and form. We still have a lot of belief in him. I know, and European football knows, that he is a really good talent.
"But he hasn't played anywhere near his potential and we're working hard with him.
"He didn't play regular minutes at Bayern. So he's gone from a very high point of winning the Euros with Portugal, to a very low point.
"Although difficult, it is a good experience for him in his career and will only make him stronger.
"And I'm sure, sooner rather than later, we'll see him come through this period. But I'll keep backing him - like all our players."
