It is clear that Chelsea have now reached to an agreement to have former Napoli boss Maurizio Sarri take over from Antonio Conte at Stamford Bridge.
Conte is expected to leave this summer following a largely disappointing campaign which ended with them missing out on Champions League football by finishing fifth in the Premier League.
He is expected to leave with a compensation of upto £17.5m in compensation should he be sacked.
Reports indicate that Chelsea have nonetheless come to terms with Sarri, but cannot agree an official deal as the 59-year-old is still under contract at Napoli, where he will be replaced by Carlo Ancelotti.
Chelsea would be forced to pay a £7m release clause if they are to appoint Sarri before May 31, so are waiting until next month to wrap up the deal.
Sarri, who spent three years in charge of Napoli, is also wanted by Russian outfit Zenit St Petersburg.
