Nottingham Forest have reportedly hit a stumbling block in their pursuit of Mainz defender Moussa Niakhate.
The French defender is a target for the Reds to provide further competition for Joe Worrall, Scott McKenna and Steve Cook. Tobias Figueiredo has already left and Loic Mbe Soh is unlikely to feature in the Premier League.
Niakhate, 25, has a year left on his contract at Bundesliga side Mainz but negotiations have hit an impasse with the two parties apart in their valuations of the athletic defender.
