Juventus legend Claudio Marchisio has told his former club that they must not sell Matthijs de Ligt or Federico Chiesa amid interest from Chelsea.
The Blues are currently in the midst of considering defensive recruits ahead of next season, with a number of their current options having uncertain futures.
Antonio Rudiger, Cesar Azpilicueta and Andreas Christensen all see their Chelsea deals expire at the end of the campaign and should the three all exit then that would leave Thomas Tuchel with seriously reduced options going into next season.
