Chelsea have held preliminary talks with Lyon over a move for full-back Malo Gusto, football.london understands.
The Blues have invested heavily in their first team this month with Benoit Badiashile, Mykhailo Mudryk, Noni Madueke, Joao Felix, and David Datro Fofana added to Graham Potter's squad. Gabriel Slonina and Andrey Santos have also been recruited, although neither has yet to make their senior debut.
Due to the injuries suffered by Reece James over the past 12 months, right-back has become a problem position for Chelsea. The club have explored several options throughout the window but Gusto – who has just 18 months remaining on his contract with Lyon – is understood to be a long-term target.
