Pisa has shown a strong interest in acquiring Calvin Stengs, a 26-year-old Dutch attacking midfielder currently at Feyenoord, where he lacks a guaranteed starting position. Feyenoord is open to facilitating the transfer to help manage the squad size for Van Persie. Stengs has not played any minutes this season and only participated in fifteen matches last season, managing to score just once. In the 2023-2024 season, he had played 38 matches and scored ten goals. Robin van Persie noted the significant competition Stengs faces, despite his attempts to prepare for roles as a number ten or right winger. The player is eager to avoid being benched and is considering a fresh start abroad. Feyenoord is looking to engage in serious negotiations with Pisa, aiming to reduce their 38-man squad. Stengs' contract is valid until 2027, and his market value is estimated at €7.00m by Transfermarkt, with Celtic and Leicester City also reportedly interested in him.
