#3 Tony Adams (Portsmouth)
It's safe to say that great players don't always make great managers. Portsmouth learnt that the hard way. Arsenal hero and former England International, Tony Adams, was appointed following a short shared caretaker stint at the club.
He was touted as a future managerial great who could do special things and he replaced Harry Redknapp amidst much fanfare following the latter's departure to Tottenham Hotspur midway through the season.
Adams' Portsmouth side had finished ninth the previous season(2007-08) and had been FA Cup winners as well. Despite financial pressures, relegation had seemed a distant prospect but Adams' disastrous reign changed all of that.
Winning only four of his sixteen games in charge of the club, Adams was sacked and replaced by youth team coach Paul Hart who guided Pompey to safety.
Adams was simply not good enough to have taken over the club considering the results his successor obtained with largely the same squad.
It could be argued that the UEFA Europa League campaign pressurized the squad and Adams' inexperience meant that he could not manage his players effectively.
There was a perceived lack of discipline in the dressing room as well, with players giving public interviews about the situation of the club and the many speculations surrounding a takeover.
Adams himself expressed his concern over the club's position but that can be no excuse for his inability to show some innovation on the pitch. Expectedly, his sides were accused of lacking ideas and being rigid with tactics.
Adams has not had much of a career in management since with brief stints with Gabala FK in Azerbaijan and Granada in Spain, ensuring a disappointing time as a coach after much hype around his skills as a player.
