Born Assisi, Italy, Ranieri was brought up in Perugia where at school he won medals in football, athletics and chess. He began his career with Perugia, making 18 appearances for Perugia's Under-18s, plus 12 games for the first team in friendlies.
On 30 June 2008, English Premier League club Tottenham Hotspur announced they had signed Ranieri following his appearances for Italy at Under-16 level and he would join up the Academy group of players. Spurs' sporting director Damien Comolli described Ranieri as '6 ft 2in and an excellent shot-stopper. His distribution and decision-making is improving all the time. He is a highly-intelligent individual and another very good young goalkeeper we have attracted to the club'.
Loan to Ipswich Town
On 9 November 2009, English Championship side Ipswich announced that Ranieri would join on loan until the end of the season as cover for regular youth goalkeeper Ian McLoughlin who was unavailable to play in the FA Youth Cup because of age restrictions for that competition, unfortunately Ranieri suffered a broken leg that ended his season early.
Loan to Basingstoke Town
Loan to Viareggio
On 8 August 2011, Italian third division club Viareggio signed Ranieri on loan until the end of the season. Ranieri made a promising start to his time at Viareggio, establishing himself as the club's first choice goalkeeper. Later however, his form dropped badly. He made several match deciding errors and misjudgements and in January 2012 Viareggio signed Massimo Gazzoli as his replacement. In the remaining games of the season he became the club's third choice goalkeeper, behind both Gazzoli and Giorgio Merlano - who he had originally displaced as first choice.
Ranieri played once in 2009 UEFA European Under-17 Football Championship qualification.
