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.
