Macken headed a last-gasp winner for City

Paul Mackenzie placed a £100 bet at 250-1 on City when they were trailing 3-0 at half-time and had been reduced to 10 men.

The 32-year-old, from Strathaven in Lanarkshire, said he just had a feeling Kevin Keegan's side were going to win.

Mr Mackenzie, who is a Manchester United fan, said he plans to use his winnings to get married.

Manchester City's best player Nicolas Anelka had been taken off injured, Joey Barton had been sent off during the game and the team had won only one of their previous 18 matches.

But City turned the match around and finally triumphed 4-3, scoring the winner in the dying seconds.

Mr Mackenzie, from Strathaven in Lanarkshire, said: "I don't know why but I just had a feeling at half-time that City were going to win so I rang up and placed the bet.

"I just felt this would be an FA Cup glory night. My fiancee, Julie, was speechless when I placed it.

"But when they scored one she sat up and began to take notice. When they scored again she couldn't handle the pressure and ran into the other room, then she heard me roar twice and knew."

The debt collector and father-of-two, who supports Rangers and Manchester United, added: "Now she's on the scrounge and everyone's my best friend."

Jennie Prest, spokeswoman for bookmakers William Hill, which took the bet, said: "This is certainly the biggest odds that we can ever remember on a half-time match.

"Paul was certainly very lucky. But another punter bet £18,000 that Spurs would win at odds of 25-1 on. Of course, he lost."

Now Mr Mackenzie plans to use his winnings to marry his partner and whisk the family away to a luxury honeymoon in Havana, Cuba.
