4. Juventus 2006
More of a demotion than a relegation, but the Italian champions were knocked down to Serie B for the 2006/07 season after being implicated by police of match fixing. The side, who were littered with some of the game’s biggest stars, were found guilty of pre selecting referees and were stripped of the title they won that year, but bounced straight back up after spending just a single season in the second tier.
