Kevin Mitchell has vowed to deliver on his third attempt at winning a world title as he prepares to get "nasty" against WBC lightweight champion Jorge Linares at the O2 Arena on Saturday night.

The two defeats of Mitchell's colourful 41-fight career have been inflicted by Michael Katsidis and Ricky Burns when the 30-year-old from Dagenham was challenging for their WBO belt.

Having been flattened by Katsidis in 2010 and Burns two years later, Mitchell has rebuilt by stringing together six successive victories to set up his showdown with Venezuelan puncher Linares.

"Jorge is a three-weight world champion and is a great fighter, but I fancy this and I know I'll beat him. I'll promise I'll be world champion this time around," said Mitchell.

"It's going to be nasty and it's going to be gritty, but that's what I'm best at. All my West Ham fans will be there."

Mitchell's collision with Linares is one of three world title fights being staged with Kell Brook's second defence of his IBF welterweight belt against Frankie Gavin topping Eddie Hearn's 'Rule Britannia' bill.
