#5 Christoph Daum
Younger football fans might not know this, but Christoph Daum was once rated very highly as a manager. The 64-year-old won the Bundesliga with Stuttgart in 1992 and was a leading candidate to take over Germany after a poor EURO 2000.
Daum had finished second in the Bundesliga three times in four years, working at Leverkusen in 1996-2000. He was set to achieve big things as a manager, but his rise came to an abrupt end when it was found out that he was a cocaine user. That shattered his reputation.
The Leverkusen side Daum built went on to reach the Champions League final a couple of years later.
However, Daum wasn't done with football management after the cocaine scandal. Besiktas, who won the Turkish league with him in charge back in 1995, gave him a lifeline and he's actually even won more after the scandal. He delivered two Turkish titles to Fenerbahce in 2004 and 2005, having also won the Austrian Bundesliga title with Vienna in 2003.
He's worked with a number of smaller teams in recent years and his last job was in charge of the Romanian national team that let him go after a disappointing World Cup qualifying campaign.
You'll do well to find a manager with more experience than Daum, who has 995 games to his name. With many league titles, he has also shown that he can be a very successful manager in the right circumstances.
