On Thursday, Rupert Murdoch said that if the CMA blocked the Sky deal, Disney would have a decision to make.
De Groote said Disney would probably have to pay more than the original £10.75 per share bid made by Murdoch in 2016 if it is required to bid again.
Disney has signalled it will not attempt to buy 100% of Britain’s biggest pay-TV broadcaster if the media regulator quashes Rupert Murdoch’s £11.7bn bid for full control of Sky.
Sky, which has more than 12 million subscribers in the UK and Ireland, closed at £9.90p per share on Thursday.
