Levante appoint Caparros to replace Martinez
"Joaquin Caparros will take charge of Levante's bench during the 2013/14 campaign," the modest Valencia-based side said on their website.
"The agreement reached ties the two parties together for a period of one season."
One of Spain's most experienced coaches, the 57-year-old Caparros has also had stints at Recreativo Huelva, Villarreal and, most recently, Real Mallorca.
Martinez, affectionately known as 'JIM', is leaving after an 11th-place finish in La Liga and a run to the last 16 of the Europa League last season.
