League Two minnows Macclesfield could earn £1million if they pull off a shock win in the FA Cup against Premiership champions Chelsea.Betbrokers, who are also spending £10,000 on bussing the Silkmen's fans to Stamford Bridge, have offered Town the figure if they manage what would be one of the greatest shocks of all time, the betting brokerage having laid a £15,000 bet at odds of 66/1. Macclesfield chairman Rob Bickerton admits the offer is a massive incentive for Paul Ince's men. He said: 'We are definitely looking to win this game and it would be a massive bonus for the club if we could do it.' Betbrokers chairman Wayne Lochner added: 'We've built a risk-management product that allows Macclesfield not only to enjoy being able to beat a team as good as Chelsea but also to see significant financial returns, all within the spirit of the Football Association. 'I think they've got a slightly better chance than 66/1. If Southend can beat Manchester United, Macclesfield are in with a shout.'
