Prince William reportedly told a fellow Aston Villa fan on Tuesday night that he plans to name his next child after midfielder Jack Grealish.
The Duke of Cambridge was at Villa Park to witness Grealish's fine volleyed winner against Cardiff City when he is said to have made the claim.
According to The Mirror, William told a supporter next to him: 'I'm going to insist the baby is called Jack... or Jackie.'
The prince and wife Kate Middleton, who is due to give birth this month, have not yet publicly revealed the sex of the their third child.
