The star duo spent small fortunes on quickly proving how the banned substances had entered their systems but other players, many of whom do not have huge financial resources at their disposal, are understandably jittery.

“A lot of the players I know are quite apprehensive,” former US Open champion Emma Raducanu told British media this month.
