Obviously Howard Kendall. He actually turned down the England job 3 times. Once after Bobby Robson left, once after Graham Taylor was sacked and once after Terry Venables.

Had it not have been for Liverpool fans getting the English teams kicked out of Europe then he'd have stayed at Everton and probably won the European Cup at least once (that's not said out of any bias, it's a very highly likely probability)

But besides him then it has to be Brian Clough. They'll never be another like him, he was a total one off. I wouldn't say he was the best manager in the business but he was in the top one.
