10 greatest managerial comebacks
#9 Ernesto Valverde (Athletic Bilbao)
Ernesto Valverde is considered a deity in Bilbao. The ant, as he was referred to during his playing days at the Basque club, began his managerial career at the youth academy in Bilbao before being promoted to coach the senior team in 2003. He led the team to a fifth-placed finish in La Liga and earned qualification for the UEFA Cup.
After impressive spells at clubs such as Espanyol and Greek side Olympiacos, he returned to help out his former club. He won Bilbao the Supercopa de Espana in 2015, humiliating FC Barcelona 4-0 at the New San Mames.
He is now all set to become Barcelona's manager following the departure of Luis Enrique.
