Chelsea trio Antonio Rudiger, Andreas Christensen and Cesar Azpilicueta face an uncertain future in west London, with Roman Abramovich's sale of the club raising questions over any potential new deals.
Abramovich has announced plans to sell the club after nearly 20 years as owner, though an opening offer has reportedly been knocked back with the Russian's advisor suggesting there is no "rush" to sell.
There has also been uncertainty over the future of Marina Granovskaia, the director who has been at the forefront of much of Chelsea's transfer and contract business over the last decade.
