Chelsea owner Roman Abramovich is said to have placed a £71million valuation on manager Jose Mourinho should any interested club look to secure his services, Express reports.
The 52-year-old has struggled immensely this season despite only being crowned champions of England during the previous campaign.
His side have already registered six loses from their first 11 Premier League matches this term as the Blues sit in 15th place.
It is believed that the club owner has already met with a shareholder from the Ligue 1 giants, but has told him to pay the mentioned amount if they want to sign Mourinho as their new manager.
Despite the performance of the squad, Abramovich is still said to be backing the Portuguese boss during his current crisis, but could eventually lose his patience if results continue to go against them.
The former Real Madrid manager only signed a four-year contract extension in the summer, meaning that if the current English champions want to terminate his deal, they will have to pay him £37.5million.
