On 8 March 2011, Caruso Lombardi was appointed as head coach of Quilmes, with the club languishing at the bottom of the table and fighting relegation. It is expected that he would remain in that role until his contract expired in June 2012. After a successful spell at Quilmes, during the night of 3 April of the next season, he signed a contract with San Lorenzo de Almagro, replacing Leonardo Madelón in the charge, after their bad results.
