Sunderland’s interest in Frank Zambo Anguissa from Napoli was described as 'very concrete'. Fabrizio Romano confirmed that Sunderland’s approach went beyond a mere inquiry, and negotiations were explored with genuine intent. Anguissa showed interest in a new challenge, but the transfer collapsed after Napoli head coach Antonio Conte personally intervened to block the deal. Under Conte's direction, Napoli made it clear that the midfielder was not for sale under any circumstances, regardless of the financial offer.

According to Fabrizio Romano, the ambitious English club Sunderland made an offer for Zambo Anguissa during the summer transfer window. Nothing materialized because Antonio Conte strongly expressed his desire to keep Anguissa. Conte's opinion was very influential in Napoli's internal decisions and in convincing Anguissa to stay.

Sunderland has approached Napoli regarding André-Frank Zambo Anguissa as part of their ambitious plans to strengthen their midfield. Fabrizio Romano reported that the move for Anguissa, who has previously played in the Premier League, aligns with Sunderland's efforts to enhance their squad following substantial investments in players such as Simon Adingra, Habib Diarra, Enzo Le Fée, Noah Sadiki, and Chemsdine Talbi, with the club having already spent over £100 million. The club's strategy involves targeting experienced players like Anguissa to bolster their competitive success. Transfermarkt has estimated his market value at 27.00 million euros.
