Porrini subsequently joined Scottish club Rangers in 1997, for £4 million and won two Scottish Premier League and Scottish Cup medals, as well as a League Cup title during his four seasons in Scotland. He started off his Rangers career at centre-back alongside Richard Gough but new manager Dick Advocaat soon moved him to right-back where he remained until he left the club in 2001. In total, he made 133 appearances for the club in all competitions, scoring seven goals, six of which came in league play in 80 appearances. He left Rangers to resume his football career in Italy at Alessandria for a season, later moving to Padova. After two seasons with Padova, Porrini joined lowly Pizzighettone in 2004 and retired after five full seasons spent with the small Lombardian club at Lega Pro Prima Divisione and Lega Pro Seconda Divisione levels, in 2009.
