Assistant manager Dean Wilkins, and first-team coaches Andy Crosby and Jim Stannard have left the club.
They have been replaced by Jesus Perez, Miguel D'Agostino and Toni Jimenez respectively.
All three coaches worked with Pochettino during his time in charge of Espanyol.
Adkins, who achieved two successive promotions with the south-coast club, was sacked last Friday, and Pochettino was immediately announced as his successor.
