Fresh information has emerged on how Maurizio Sarri secured his much-awaited release from Chelsea for him to join Juventus after a prtracted negotiations with the Stamford Bridge club.

The Italian coach finally received Chelsea’s nod to become Juventus manager after the Italian champions agreed a £7million compensation fee with Chelsea on Thursday night.

According to the Daily Mail, the two clubs struck a deal after further talks between Chelsea director Marina Granovskaia and Juventus sporting director Fabio Paratici, who flew to London to try and find a resolution, on Thursday.

Sarri, 60, had two years left on his £5m-a-year Chelsea contract. And the Blues were refusing to cave into Juventus’s attempts to land Sarri on the cheap.

At one stage Juve hoped they would land Sarri for nothing as they usually refuse to pay compensation for managers.

But Chelsea dug their heels in and forced Juve to cough up in another negotiation win for Granovskaia, who was holding out for as big a compensation fee as possible, a week after she made Real Madrid agree a deal worth up to £150m for Eden Hazard despite the Belgian having just one year left on his contract.

Sarri is now clear to sign the three-year deal he agreed in principle with Juventus last month after they made him their top choice to replace Massimiliano Allegri.

The former Napoli boss will be announced as the new Juventus manager today.

He will earn up to £6.2m a year as manager of Juventus and his exit will be rubber-stamped in the next 24 hours, while Chelsea will step up their attempts to replace him with Derby boss Frank Lampard the leading candidate.

Derby are braced for an offer for Stamford Bridge legend Lampard who would bring former Blues midfielder and youth coach Jody Morris from Pride Park back to their old club as his assistant.
