5. Héctor Cúper – Mallorca
Certainly one of the lesser-known individuals on the list, Cúper has an impressive managerial dossier. After modest spells in charge of Spanish outfits Huracán and Lanús, the Argentine achieved one of the greatest feats of his career with Mallorca, who he propelled into the Copa del Rey final in his first season (1997-98).
The club would lose to Barcelona, but Cúper quickly established a solid unit that would go on to win the 1998 Spanish Supercup as well as a remarkable 3rd place finish that same season. This also ensured Mallorca of an appearance in the prestigious Champions Leauge.
Reasonable success followed for Cúper after he left Mallorca for Valencia in 1999. He would go on to manage Inter Milan also in his time away, during which Mallorca would struggle. Rooted to the lower end of the league ladder at the start of the 2004/05 campaign, Mallorca requested Cúper to return and the now 60-year-old saved the club from relegation.
Results, however, didn’t improve the following season however and Cúper resigned once again in early 2006.
