Gary Lineker admits he has had second thoughts about his promise to present Match of the Day in his pants now that Leicester City are on the verge of winning the title.

The former Foxes and England striker has caught cold feet in recent weeks, having vowed last December to appear on the programme in his underwear if his boyhood club pulled off the unlikely achievement.

Leicester, who were 5,000-1 outsiders for the title at the start of the season, will be crowned champions if they beat Manchester United this coming Sunday, following Tottenham Hotspur’s failure to beat on West Bromwich Albion on Monday night.

Lineker has reservations about the stunt but, having discussed it with BBC producers, he is now resigned to fulfilling his promise.

"You'll have to wait and see. I've kind of said I'll have to do it," the 55-year-old presenter told the Radio Times. "The conversation's been had. I've told them many times, 'Please tell me I can't do it'.

Top sporting forfeits Show all 6 1 /6 Top sporting forfeits Top sporting forfeits Rodney Marsh's close shave Rodney Marsh had the honour of playing for several big teams as well as England during the 1960s and 70s. But his declaration that he would have his head shaved if Bradford managed to avoid relegation from the top flight went the wrong way in 2000. The Bantams duly survived and Marsh had his flowing locks taken off on the pitch at Valley Parade in front of the delighted Bradford fans. Top sporting forfeits Serbia's Davis Cup team shave their heads A decade after Marsh's hair-razing act, Novak Djokovic and his Serbia team were getting theirs shaven - albeit in happier circumstances. The Serbians had promised to shave their heads if they secured the Davis Cup crown and, after a 3-2 win over France in December 2010, treated fans to the unique post-match celebration. 2010 Getty Images Top sporting forfeits Usain Bolt wears Arsenal shirt Regular fans donning shirts of rival teams is nothing new. But Manchester United supporter Usain Bolt stepped it up a notch when in October 2015 he lost a bet with Mexican TV presenter and Arsenal fan Patty Lopez. The world's fastest man posted the forfeiture photos of him in a Gunners shirt on his Instagram account, complete with name and his world-record time of 9.58 at the back. Top sporting forfeits All Blacks ride a mile high Rugby being the big deal that it is in Australia and New Zealand, rival national airlines Qantas and Air New Zealand were understandably fired up for the 2015 Rugby World Cup final between the two nations. A Twitter bet was fixed thus: the crew of the losing side to don the winner's kit - this after suggestions to repaint the loser's fleet were rejected. The All Blacks defended their world crown with a 34-17 win, and the rest was history. Qantas Top sporting forfeits Kate Lundy's showboating comes back to bite her Politicians have never shied away from a bit of verbal sparring, but Australian sports minister Kate Lundy was forced to pay up after losing a bet with her British counterpart Hugh Robertson during the 2012 Olympic Games in London. Lundy backed the Australians to win more medals than the host nation, but ended up having to do a 1,000-metre row on Dorney Lake in a Team GB kit. Getty Top sporting forfeits David Campese's walk of shame Back to Australians and rugby, and the 2003 World Cup won by England. Former Wallabies winger David Campese ended up having to wear a sandwich board with the message "I admit, the best team won" and walk down Oxford Street in London, this after his prediction about England being a boring side. As England captain Martin Johnson lifted the trophy following a 20-17 victory over Australia in the final, Campese was getting ready to eat humble pie. Getty

"When I sent the tweet in December I categorically knew there was zero chance that (Leicester) would win.

"I'm in good shape. For an old b*****d. I'll probably work out for the two weeks beforehand very, very hard."

While speaking exclusively to The Independent, Lineker denied ever promising to do the entirety of the programme in his briefs.

“I certainly never said anywhere in that tweet that I would do the whole show," he said.

Claudio Ranieri's side have only shown brief signs of wavering during the title run-in and maintained their championship-winning form with a 4-0 home victory over Swansea City on Sunday.

Three points at Old Trafford would seal the first top division league title in the club's 132-year history. Only two teams - Norwich City and Southampton - have beaten Manchester United away from home in the league this season.
