Having featured in last seasons 'Great Escape' Ledesma is no stranger to Saddlers fans and his return should be a major boost to the squad.
Following last season's heroics 'Emmy returned to Argentina with his girlfriend, and despite being offered a fresh Saddlers deal he inked a one-year contract with Argentine outfit Defensa y Justicia, the club where he began his career.
With his girlfriend now expecting a child it seems 'Emmy is now seeking the stability Walsall can offer him and his growing family.
Clearance has already been received and he will feature in Saturdays crunch tie away to relegation rivals Yeovil, and wear the number 28 shirt.
