Tony Bellew works on hooks and uppercuts for Haye rematch

Six weeks of training and up to 12 gruelling rounds are all that stand between Tony Bellew and the chance to achieve his aim of ending the career of David Haye.

The two former cruiserweight world champions clash at London’s O2 Arena next month, less than a year on from their dramatic first encounter when Bellew stopped Haye in 11 rounds.

Both fighters are in camp for the rematch and on Monday the Liverpool fighter posted a video of him practising his hooks and uppercuts ahead of the December 17 showdown.

‘Always working always improving,’ the British fighter wrote alongside the video on Instagram

Bellew shocked the boxing world when he stopped a badly-injured Haye at the O2 back in March.

The heavyweight grudge-match was marred by bad blood and sinister threats made in the build up.

Eight months on, the two British fighters are set to renew their rivalry, with Bellew keen to send the London fighter into retirement for good.

‘I want to win more than anything,’ the Liverpool fighter last week about the Haye rematch

‘I want to win more than anything, but I’ll take great pleasure in knowing I was the man who put the final nail in the coffin of David Haye’s career,’ he said last week.

‘He should never have said the things he said: saying my kids are going to visit me in hospital.

‘It’ll never go away now that he’s said it. That gob***** made out like it was going to be glorious to hurt me.’
