The transfer mill is churning once again, with Rennes believed to be lining up a move for Goncalo Calisto Oliveira, the defender from Sl Benfica. Sources close to the club suggest they are exploring options to reinforce their squad ahead of the run-in. Barcelona have not withdrawn their interest and could still influence the outcome. Across the season 25/26, Rennes have let in 35 goals in 24 (1.46 per game), roughly in line with the Ligue 1 average. Goncalo Calisto Oliveira would be expected to give them some extra stability and depth for the tougher stretches of the season.
