Lyon fullback Malo Gusto has passed his Chelsea medical in London.
The Blues have struck a 26.3million deal with Lyon to sign the highly-rated defender, who will stay on loan in France for the remainder of the season.
Chelsea were keen to bring in a right-back alternative to Reece James and identified 19 year-old France under-21 international defender Gusto.
The Blues were met with initial resistance to their interest from Lyon with president Jean-Michel Aulas publicly declaring Gusto 'will continue to play' for Lyon until the end of the season.
He will join Christopher Nkunku as a pre-agreed summer arrival after Chelsea also finalised a 53m deal to sign the France forward from RB Leipzig.
