Professor Stephen Hawking - who has dealt with some of the most complex questions in theoretical physics - reveals to BBC Newsnight his tip that striker Daniel Sturridge will be England's top scorer in this summer's World Cup, ahead of Wayne Rooney.

Professor Hawking told Newsnight: "It's clearly between Rooney and Sturridge. I'm going to say Sturridge. You don't need to be a great mathematician to work this out. If you look at goals per minute in this year's Premier League then Sturridge scores once every 108 minutes, compared to Rooney once every 144 minutes. The ratios were similar last season. In addition to this, I think psychological factors will be on Sturridge's side. He is in the form of his life and Rooney is playing with the albatross of never scoring in the World Cup finals around his neck."
