The on-loan Rio Ave frontman has enjoyed a sensational short-term stint in Scotland since arriving from Portugal in January.
The 21-year-old struck just seven minutes into his debut in the Scottish Communities League Cup semi-final victory over Clydesdale Bank Premier League champions Celtic.
Then he bagged another goal as the Buddies overcame Hearts 3-2 in the final to secure their first major trophy for 26 years.
All in all, Goncalves has struck six times in 11 outings for Danny Lennon's men but that form has convinced his paymasters in his homeland to recall him once his loan spell is up and try to cash in on his impressive figures.
Lennon admitted, however, that he has not given up hope of securing another loan spell and the former Nice attacker admits his future destination is uncertain.
Asked if he was preparing for his final four games in black and white, Goncalves told Press Association Sport: "It's the last four games of the season - after that, I don't know.
"If the opportunity was there to stay, I'd like that because I have really enjoyed my time in Scotland. But all I know is that Rio Ave want to sell me.
"You never know what could happen. I'm not sure about another loan deal but if they told me to come back here to St Mirren, I'd be happy. The fans really like me and I feel good here.
"If I go, though, I will miss Scotland, and especially the St Mirren fans. I really love the St Mirren fans."
