Boca Juniors appoint Fernando Gago as new head coach
Gago replaces Diego Martinez, who resigned last month after three consecutive defeats in Argentina's top flight.
"Gago signed his contract with Boca and is the new Xeneize coach. Welcome home, Fernando," Boca wrote on X.
The former defensive midfielder had spells with Real Madrid, Roma and Valencia before returning to Argentine football in 2013 to play for Boca once again. He ended his playing career with Velez Sarsfield.
As a manager, he led Racing Club to the Argentine Champions Trophy and the International Super Cup after a spell at Aldosivi de Mar del Plata.
Gago, who took over at Chivas in December, had said on Thursday he would leave the Mexican club.
