Egil Olsen
The Norwegian was a surprise choice when he was appointed manager of Wimbledon in 1999. He had spent eight years in charge of Norway and had a brief spell at Valerenga before being handed the job at Selhurst Park.
Olsen struggled to get the best out of his players, and he was sacked before the club’s relegation was confirmed, ending their 14-year stay in the top flight.
