The 51-year-old's United Kingdom investor visa expired some weeks ago.
Chelsea issued a statement on Thursday, May 31, saying work on their new stadium in west London would be suspended indefinitely because of the "unfavorable investment climate". "No further pre-construction design and planning work will occur", Chelsea said in a statement in London.
These are uncertain times in the future of our football club.
'The decision was made due to the current unfavourable investment climate'.
"He will want to clarify any misunderstanding and speculations".
Nevertheless, without a visa, Abramovich will not be allowed to work in England.
The club was aiming to complete the stadium in 2021 and was considering a move to Wembley Stadium during the redevelopment period, although that move may have been affected by the recent bid from U.S. businessman Shahid Khan to buy the national stadium.
Chelsea have confirmed that plans for their new stadium have been put on hold.
The Blues are looking to redevelop Stamford Bridge and were hopeful of taking up residency of their new stadium in 2021.
Arsene Wenger's success in English football more or less stopped when Roman Abramovich took over Chelsea, and now his belated exit is laced with a deep irony.
That may also account in part for the delay over Chelsea's managerial situation since the FA Cup final nearly two weeks ago.
The situation with Sarri was already complicated by a £7million release clause at Napoli but Chelsea are now more alarmed by an exchange the Italian had with new Italy manager Roberto Mancini.
Chelsea are expected to move into gear when director Marina Granovskaia returns from a break next week but Sarri no longer appears to be first choice to succeed Conte amid concerns about his past.
The state of limbo is a huge concern to fans who have seen Arsenal replace Arsene Wenger with Unai Emery and Liverpool complete the signing of Fabinho from Monaco.
