Anthony Joshua must prove he can handle the pressure and distractions of holding world heavyweight titles, says former champion Mike Tyson.

Joshua, 27, knocked out Wladimir Klitschko in May to add the WBA title to the IBF strap he already held.

But Tyson – a two-time world heavyweight champion – has warned the position can be “a crown of thorns”.
