A Premier League investigation into Chelsea's transfer dealings during the Roman Abramovich era is looking at secret payments made by the club when they signed Willian and Samuel Eto, according to reports.
The former Blues pair completed their transfers to Chelsea in August 2013 from Russian side Anzhi Makhachkala and have been flagged for further investigation, as claimed by The Times.
Abramovich sold Chelsea to Todd Boehly last year in a £4.2billion deal after the government sanctioned the former owner in March following Russia's invasion of Ukraine.
