Claudio Ranieri waved goodbye to Cagliari and brought the curtain down on a near four-decade club coaching career with Thursday's 3-2 defeat to Fiorentina cruelly inflicted in the 13th minute of added time.However Thursday's defeat made little difference to Ranieri or Cagliari as last weekend he saved from relegation the same club he brought up from Serie B last season and with whom he rose to prominence in the late 1980s.
