Surging heavyweight Tom Aspinall has backed himself as one of the most "devastating punchers" the UFC has ever seen.
Aspinall faces a big step up in competition at UFC London on March 19 when he headlined the card against No.5 ranked Alexander Volkov.
The Brit was initially booked to face Shamil Abdurakhimov on the card, but the promotion pulled him from the fight to meet 'Drago' in the main event.
