French defender Jeremy Petris, 27, has transferred from Charleroi to Watford. This move is part of a significant outflow of players from Charleroi, following their exit from the Conference League qualifiers against Hammarby. In addition to Petris, several other players have left the club, including Youssuf Sylla, who moved to Jagiellonia, and Freddy Mbemba and Mondy Prunier, who were loaned out to Guingamp and Eupen respectively. Charleroi is now looking to bring in replacements in the coming days. His market value is estimated by Transfermarkt to be €2.80m.
