Belluschi began playing professionally at Newell's Old Boys in 2002, with whom he won the 2004 Apertura Championship. He moved to River Plate in 2006 and with the departure of Marcelo Gallardo to Paris Saint-Germain following the 2006 Apertura, he was named team captain, a position he would fill for two years. He then joined Olympiacos for reported €6.5 million in early 2008. On 6 July 2009, Porto purchased Belluschi's playing rights and 50% of his economic rights for €5 million. The other 50% was owned by private investment companyRio Football Services Ltd. He signed a contract until 2013 with a release clause of €30 million. In 2012, Belluschi was sent on to Genoa under a purchasing option of €3.5 million, or €5 million if the club qualified for the UEFA Europa League. In summer 2012, Porto sold its 50% ownership of his economic rights for €1.05 million. On 10 July 2015, Cruz Azul signed Belluschi on a free transfer. His salary was set at €1.1 million. He debuted for the side as a substitute in the 61st minute for an injured Marc Crosas in the Clasico Joven. He did not receive his international pass until the Clasico Joven, which was why he did not participate in any league matches up to that point. He failed to score for Cruz Azul, having a penalty saved by Atlas goalkeeper Miguel Ángel Fraga on matchday 11. On 26 January 2016, San Lorenzo signed the then-32-year-old Belluschi on a free transfer.
