Chelsea Football Club owner Roman Abramovich bought two paintings that were sold at record-breaking auctions last week, according to reports.
Lucian Freud’s Benefits Supervisor Sleeping sold for Â£17.2m on Tuesday, followed by Francis Bacon’s Triptych, which fetched Â£43m just 24 hours later.
The Art Newspaper quoted sources saying the London-based Russian billionaire was the buyer of both paintings.
A spokesman for Mr Abramovich declined to comment.
He said: “We don’t get into personal matters.”
The life-sized Freud painting of a sleeping, naked woman, titled Benefits Supervisor Sleeping, sold for $33.6m (Â£17.2m) at Christie’s in New York.
Christie’s described the work, which shows Jobcentre supervisor Sue Tilley asleep on a sofa, as a “bold and imposing example of the stark power of Freud’s realism”.
It set a new world record price for a work by a living artist.
