#3 Marcelino

A former Spain U-21 international, Marcelino made a go of his playing career in the midfield for four different clubs over nine years making a combined 203 appearances all in Spain between 1985 to 1994.
Marcelino managed a host of clubs in the Spanish second and third divisions achieving success and promotions as his name in the Spanish football system became bigger. His most notable spells were at Racing Santander and Zaragoza.
Marcelino's success rate in achieving promotion meant that he was one of the best-paid managers in Spain but the big clubs did not come calling till he was given a shot with Sevilla, with whom he had a disastrous season.
In 2013 he joined the then relegated Villarreal side and turned around their fortunes in three seasons. Villarreal finished in the European places in all three seasons under him in the La Liga, an impeccable achievement for a side that had been relegated the season he took over.
He was surprisingly sacked just before the 2016 season began and after a year on holiday, he joined Valencia. So far Marcelino has turned Valencia's fortunes around, with the club in second place and looking no signs of slowing down.
