KELL BROOK has vowed to retire if he loses to Hector Saldivia at the weekend.

Unbeaten Brook faces the Argentinian in an IBF welterweight title eliminator in his hometown of Sheffield knowing victory will keep him on track to face Amir Khan next year.

But Brook, 26, admits it will be ­ curtains for his career if he is defeated.

He said: “People keep saying I have ­talent and I know how much hard work I have done in this training camp.

“If I can’t get rid of guys like Saldivia, I don’t deserve to be at this level.

“That is why I’m saying I will pack up if I don’t beat him.”

IBF world champion Randall Bailey risks his title against Devon Alexander in Brooklyn this weekend and if Brook comes through at the Motorpoint Arena, he is guaranteed a shot against the ­winner early next year.

But an even bigger fight on the ­horizon would be a potential £5m ‘Battle of ­Britain’ against Khan.

Khan has teased Brook over his ­credentials and the pair rowed when they appeared on TV earlier this month.

Brook said: “I have got to come through this fight with flying colours and show why people call me the ‘Special One’.

“I am not trying to do anything for Khan this weekend but there is pressure on me to perform.

“I want to show myself and the fans why people are banging on about me ­going on to achieve great things.

“I want to make a statement and ­impress against Saldivia so people put me up there with the elite of boxing.”

Brook has improved his diet and must do likewise with his stamina after just getting through his 12-rounder against ­Carson Jones in July.

Much of his training camp has been spent in Fuerteventura in the ­Canaries, working with buddies from Dominic ­Ingle’s gym.

On the undercard in ­Sheffield, Robin Reid and Kenny ­Anderson will ­battle for the British ­super-middleweight title.

The belt was vacated by George Groves due to ­injury.
