According to multiple reports, Atletico are in formal negotiations with Lyon over the signing of Nicolas Tagliafico. The defender has been a target for some time, and talks are said to be intensifying as the window progresses. The player remains under contract, but movement looks increasingly likely the longer talks go on. Juventus may look to intervene if talks continue without resolution. With only 3 goals conceded in 3 (1.0 per game), Atletico have been one of the stronger defences in the LaLiga this season.. Nicolas Tagliafico would be asked to keep that standard and provide dependable cover when needed. Lyon continue to be linked with Matt O'Riley and Lois Openda while Atletico are also rumoured to be tracking Malo Gusto, Issiaka Kamate and Thiago Helguera. More on this story as it develops.
