4) Dick Advocaat, Sunderland
The first success in this list, the 67-year-old was given just a handful of games to save the North East club from relegation, and ended up keeping them up with a match to spare. The Black Cats are the 21st side the Dutchman has managed, including the Netherlands national team, PSV Eindhoven, and Rangers. He will also be spending an extra year there now, after persuading his wife to live in Sunderland for another year!
