While Seys is firmly on the radar, Manchester United could still revisit their interest in Newcastle United defender Hall. The club were previously put off by a £75 million asking price in the final days of the window.
However, Tyrone Marshall, chief Manchester United correspondent for the Manchester Evening News, stated on the 'United! United! United!' YouTube channel: "It’s hard to say 8 months out, but I think there’s a good chance they sign Lewis Hall next year." Until then, Seys represents a strong alternative.
