Since 2008–09 season, Agazzi has been the first choice goalkeeper, after the departure of Generoso Rossi.
On 9 July 2009 Cagliari Calcio signed the goalkeeper from Serie B club Triestina in a joint ownership deal, for €575,000 in 4-year deal. However, he would continue to play for Triestina until June 2010.
However, on 1 February 2010 he returned to Cagliari, 5 months earlier, for €1.2 million in temporary deal. Triestina also acquired Triestina outright for €500. Co-currently, Triestina signed Alex Calderoni as replacement. On 21 June 2010, Cagliari signed the keeper outright from the relegated side for €50,000. (later Triestina re-admitted to Serie B)
He became the first choice goalkeeper for Cagliari in 2010-11 season after the original one, Federico Marchetti, was frozen by the club as punishment. Ivan Pelizzoli, former internationals, also hinted he is the backup of Agazzi instead of Marchetti at the start of season. In July 2011 he signed a new 3-year contract with the Serie A club. Cagliari and Agazzi did not form any agreement on new contract, thus in January 2014 Agazzi was transferred to A.C. ChievoVerona, with Marco Silvestri moved to Cagliari in temporary deal.
On 22 May 2014, A.C. Milan announced the summer signing of Agazzi from Chievo Verona, with the transfer taking effect from 1 July.  News of Agazzi's arrival came just a day after the renewal of Christian Abbiati's contract at the Milanese based club. Agazzi would replace Marco Amelia who was not offered a contract extension by Milan.
