British billionaire Jim Ratcliffe has launched a late bid to buy Chelsea for 4.25 billion pounds ($5.3 billion).

The bid for Chelsea launched by Boston Celtics co-owner Steve Pagliuca has added Canadian sports tycoon Larry Tanenbaum ahead of Thursday’s expected deadline for improved offers for the Premier League club.

Final bids are being prepared for European champion Chelsea as the process to end the ownership of sanctioned Russian oligarch Roman Abramovich steps up.
