On 22 January 2013, Gonçalves signed on loan with Scottish Premier League club St Mirren until the end of the 2012–13 season. The day after signing, he was quoted in the local newspaper Paisley Daily Express that he could be "the next Drogba".

Gonçalves scored his first goal for the club on his debut in the Scottish League Cup semi-final in a 3–2 win over Celtic at Hampden Park, with his being the club's first goal against the Glasgow side since March 2010. Three days later, he made his first Scottish Premier League appearance against Inverness Caledonian Thistle, nutmegging the goalkeeper in a 2–1 victory. In his first Scottish Cup appearance against St Johnstone, Gonçalves scored both goals of a 2–0 victory. He scored another goal against Celtic at St Mirren Park in a 2–1 loss in the sixth round of the Scottish Cup.

On 17 March 2013, Gonçalves played in the Scottish League Cup final against Hearts where he scored the equalising goal and provided an assist for Conor Newton's third in a 3–2 victory Buddies' first League Cup and their first major trophy since 1987. Shortly after scoring, he lifted his jersey, which had the inscription "Forca Fábio Faria" ("Come on Fábio Faria"), dedicating a goal to a player whose career ended after a heart condition. Gonçalves was then booked by the referee.

In a 1–1 draw against Celtic on 31 March, Gonçalves caused controversy when he dived to win the penalty after being fouled by Emilio Izaguirre, with television pictures proving that there was no contact. After the match, he was given a two-match ban by the SFA, following an issue of complaint for his action of diving, which he accepted. He told BBC Scotland that he would be happy to make a return to St. Mirren in the future. The club was willing to make his transfer permanent, but Rio Ave announced that this would not be the case, and said that such a deal would cost £400,000.

Gonçalves was born in Bissau, the capital city of Guinea-Bissau, but moved to Portugal with his family at the age of three. He began his football career with Boavista. Gonçalves spent three years at the club before venturing to France to sign with Nice after being invited for a trial at the club. Prior to signing with the club, he drew interest from English club Liverpool. Gonçalves spent two years in Nice's youth academy before earning promotion to the club's reserve team in the Championnat de France amateur 2 for the 2010–11 season. Following a successful half season at reserve level, he was called up to the senior team in January 2011 and made his professional debut in a 2–0 defeat to Bordeaux, appearing as a substitute. That was his only senior team appearance of the campaign.

Though born in Guinea-Bissau, Gonçalves is a naturalised citizen of Portugal. He has represented them at under-17 level. In 2010, he was called up to the Portugal under-20 team to participate in training sessions as the team was preparing for the 2011 FIFA U-20 World Cup. Gonçalves, however, showed up to the camp out of shape and was, ultimately, not considered for the tournament by coach Ilídio Vale.
