Roman Abramovich reportedly has his concerns over the 'formal bid' for Chelsea Football Club that was submitted by Todd Boehly and Hansjorg Wyss on Tuesday.
Abramovich confirmed last week that he would be selling Chelsea after 19 years as the club's owner, with the Russian businessman asking for £3billion.
There have been a number of parties who have expressed their interest in purchasing the west London club, with Boehly and Wyss looking like serious candidates at the moment.
Boehly reportedly attempted to buy the Blues in 2019 for £2.2bn, but was unsuccessful and he has now teamed up with Swiss billionaire Hyss.
However, as per PA news agency, Abramovich has his doubts over the offer that was submitted to him on Tuesday.
Raine Group are the organisation in charge of the bidding process when it comes to Chelsea, but Abramovich will still have plenty of say on the matter.
The report adds that numerous officials involved in the bidding process have been left 'bemused' by so many parties making their interest in buying Chelsea public.
As reported on Tuesday, Abramovich is after an owner, or a consortium, who will continue his investment into the Blues' squad and also the redevelopment of Stamford Bridge, or have plans for a brand new stadium.
It is not yet reported what Abramovich's concerns over Hyss' and Boehly's bid are.
Elsewhere, there could be a rival party about to test Abramovich's resolve with another offer, according to the Daily Mail, who say that Nick Candy is preparing a £2.5bn bid before the end of the week.
The 49-year-old businessman is a known Chelsea supporter and the report claims that he already has plans for a £1.5bn Stamford Bridge rebuild.
"Nick Candy is actively exploring a number of options for a potential bid for Chelsea Football Club," a spokesperson for Candy said to the Daily Mail.
"Any bid would be made in conjunction with another party (or consortium) and we have serious interest from several international partners."
