Rennes is reportedly set to sign Portuguese defender Gonçalo Oliveira from Benfica's reserve team. The transfer for the 19-year-old central defender is valued at approximately 3.5 million euros. Oliveira was a notable player in the Youth League this season but has not yet appeared for Benfica's senior side, and would consequently make his professional debut with the French club. The Portugal U21 international, for whom he has 4 caps, made 24 appearances for Benfica B in the 2025/2026 Liga Portugal 2 season, scoring 2 goals and registering 1 assist. His current market value is €2.00m, according to Transfermarkt.
