Chelsea is interested in Ousmane Diomande and wants to acquire him during this transfer window. The player is rated at €80m.

Ousmane Diomande has emerged as an important figure in the center of defense for Sporting, particularly impressing during the match against Manchester City where he defended Erling Haaland. His performances have caught the attention of many, with Kenneth Andersen, a former coach and current scouting coordinator at Mafra, noting that Diomande is drawing interest from major European clubs. Andersen reported that substantial financial figures are being discussed for a potential transfer, highlighting the significant interest in Diomande from leading clubs.

Ruben Amorim, who will soon become the head coach of Man United, is keen to bring Ousmane Diomande to Old Trafford to strengthen the defense. The Sun reports that Man United will need to meet Diomande's £70m release clause to sign him. Football analyst Ben Mattinson believes Diomande could become 'a monster in no time.'

Sporting CP made an effort to keep Diomande in the squad.
