Margaret Court says Serena Williams played in ‘much easier’ era

• Australian has record of 24 major titles to American's 23
• Court says she has been affected by views on same-sex marriage

Court holds the record for grand slam singles titles with 24, one ahead of Williams. But it is Williams who is usually described as the greatest player of all time.
