Sigali came through the youth system at
Nueva Chicago, club from the Western part of the
Argentine capital, to make his professional debut in 2006. With Nueva Chicago Sigali formed part of the team that was champion of the
Primera B Nacional (Argentine second division) 2006 Clausura, and ascended to the
Argentine Primera. He played the
2006-07 season with Chicago in Primera as a central defender along
Nicolás Sánchez. However, the club was relegated after losing the playoff to
Tigre. Subsequently, Sigali was bought by Spanish side
Villarreal. However, he was immediately loaned to
Lanús in 2007, as they needed more defensive cover due to injuries of other key players. He helped his new team to win the
Apertura 2007 tournament, Lanús' first ever top flight league title. In 2008, he joined newly promoted
Godoy Cruz, on loan. The deal was made permanent in 2010, when Godoy Cruz bought 50% of Sigali's rights. == International career ==
