The Saracens chief Eddie Jones says the impact of so many players being forced out at the end of the English rugby season caught up with his team during their 21-15 Premiership loss to Harlequins
The former Wallaby coach and at least 15 players are set to leave the London club at the end of the season.
The new South African owners are bringing in several signings from the Republic, as well as a new coach in Brendan Venter.
That's angered the Harlequins director of rugby Dean Richards.
The former England number eight says turning a club like Saracens into a South African franchise is disgraceful and should be stopped.
