Nottingham Forest's 'concrete interest' in Birmingham City's key player – Could move in January

Nottingham Forest showing concrete interest in Birmingham City centre-back Phil Neumann, 29, who could move in January with a fee around €3.5m.

Phil Neumann has attracted attention from multiple clubs after impressing for Birmingham City this season. The German centre-back, signed on a free transfer in 2025, has made 17 appearances this campaign with two goals and an assist, continuing the form that saw him make 35 appearances in his debut season.

Sky Deutschland reports Neumann is now considered indispensable by Birmingham City manager Chris Davies. His performances have drawn concrete interest from Nottingham Forest in the Premier League and Fiorentina in Serie A, with the 29-year-old described as being on the verge of a career step up.

Neumann has over 19 months remaining on his contract and is valued at €3.5m by Transfermarkt. Birmingham City signed him for free, so any sale would represent a profit. Nottingham Forest would need to convince both the club and the player to complete a move in the January window.
