Geny Catamo is reportedly at the centre of ongoing transfer discussions between Sunderland and Sporting CP. The midfielder has attracted serious transfer interest in recent weeks, and talks are now in progress to see if there's a deal to be done. Sources close to the deal suggest negotiations are active, with both sides working to find common ground over the player's potential move. Talks are underway, and with no competition emerging, Sunderland are seen as the sole contenders for the player's signature. Sunderland's 26/27 record of 2.0 goals conceded per game shows they're missing balance in midfield. Someone like Geny Catamo could give them more structure and help them manage games. Sporting CP have also been linked with Mohamed Toure, Karim Coulibaly and Nestory Irankunda while Sunderland are reportedly monitoring Igor Paixao, Marc Casado Torras and Dayann Methalie.
