Mark McGuinness

In August 2026, it was reported that Sheffield United's manager stated the club paid £5 million (approximately €6 million) for the player's transfer from Luton Town in September 2025. Multiple reports from May to August 2026 cite his current Transfermarkt value at €7.00m. A previous completed transfer from August 2024 is also mentioned, where Luton Town reportedly paid Cardiff City €11.7M.

Our valuation is driven by reports that Sheffield United paid approximately €6 million (£5 million) for Mark McGuinness in 2025 and are now looking to sell him one year later after a disappointing season. While his market value is estimated at €7 million and he commanded a higher fee in 2024, his current transfer-listed status suggests the club will likely accept a fee slightly below their initial investment to facilitate a move.
