Mainz boss Bo Svensson has spoken about the possibility of losing Nottingham Forest target Moussa Niakhate.
The Reds are said to be back in talks over a move for the centre-back, as head coach Steve Cooper looks to strengthen his defensive ranks. A fee upwards of £10m has been mooted, after a difference in valuation had previously been a stumbling block.
The skipper has been a key figure for Mainz, making 33 appearances and scoring four goals last season. With 12 months left on his contract, he was linked with Everton, Newcastle United and West Ham United earlier in the year.
