Ranieri is not a winner , he is a survivor who can let a team survive from religation like he did with parma , but you cant win anything with him since he dont like creativity and attacking , he like to play it safe all the time.
look at his career maher, sure he aint a winner but he aint a fighter either. ignore parma because that was teh exception to the rule.
calgiari- promoted from serie C1 to serie a
napoli-finished 4th but introduced Zola to teh team
fiorentina-promoted from serie b and wn coppa italia and italian supercoppa
valencia-qualification for CL and coppa del rey success. brought in canizarez and lopez as well as bringing through mendieta,albelda,angulo,etc.... he pretty much lay down the foundations that valencia's success was built on
at chelsea he took over a team in financial trouble and improved their point tally evry year before the abramovich takeover. he brought through john terry and signed lampard,joe cole, makelele. again the foundations were laid in place for his predecessor
back at valencia he did struggle but helped set up a squad that quique sanchez flores prospered with..
basically he may never have won the league but do not underestimate his ability to build a squad, and to class him as a relageation struggler is to show a complete lack of football knowledge
