Esports has an estimated global audience of 200 million people, and this year it's set to surpass $1bn in revenue according to a report by analytics company Newzoo.

Professional esports organisation Fnatic has set up a new academy for students hoping to become the next top-earning gamer.

Matthew Coombs and Thomas Willis are academy players on the League of Legends team.

Thomas says full-time gaming involves "a lot of hard work and sacrifice".

"One of the things people say that annoys me the most is: 'You're really lucky to be able to do something that you like.'"

"I usually actually end up working longer hours than they do."
