Chelsea have reportedly lined up Monaco left-back Fode Ballo-Toure as a plan B in case prising Ben Chilwell away from Leicester proves to be too expensive.
The Blues are in the market for a new left-back for next season, with doubts over the futures of both Emerson Palmieri and Marcos Alonso.
Brazil-born Italy international Emerson and former Fiorentina full-back Alonso are both being linked with moves back to Serie A, with two former Chelsea coaches behind the bids.
Maurizio Sarri would like to take Emerson to Juventus, while Antonio Conte is keen on a reunion with Alonso at Inter Milan – although he also has Palmieri on his shortlist, having originally brought him to Stamford Bridge.
The most likely replacement, should either of the duo depart, has seemed to be Ben Chilwell so far, with the Leicester star having firmly established himself as first-choice in the position for his club and at international level with England.
