Amnesty International wants to see a change in the takeover rules.
Amnesty International has written to the Premier League to request an "urgent" meeting with its chief executive on proposed changes to takeover rules.

They've highlighted human rights issues linked to the kingdom.
The takeover was 80 percent financed by Saudi Arabia's Public Investment Fund, whose chair is Crown Prince Mohammed bin Salman.
