Bournemouth is in the mix to sign Ousmane Diomande, a 22-year-old defender from Sporting, as the summer transfer window gains momentum. Daniel Farke's side has made contact for the Ivory Coast international, alongside Chelsea and Leeds United. The Cherries, having qualified for the Europa League next season, will face stiff competition from the Blues and the Whites, who are also vying for Diomande's signature. According to Top Mercato, the 'bidding war is on' to secure the player, with Sporting willing to sanction a move for an offer exceeding €40-45m. Diomande signed a new contract at Sporting until 2030 and is valued at €42m, as per Transfermarkt. Agency Roof represents the Sporting defender, who has played 2,302 minutes from 31 matches this season. The player is currently with the Ivory Coast at the World Cup.
