Carrusca was a regular for Argentinian club Estudiantes before joining Galatasaray in Turkey and Mexican giants,Cruz Azul. He is a former Argentinian youth international and teammate of the likes of Carlos Tevez, Javier Mascherano and Pablo Zabaleta.
He will not take up a visa spot at the Wanderers, having spent five seasons with Adelaide United and becoming an Australian citizen last year, and will be eligible to play in Sunday's away match against Wellington Phoenix. Carrusca's arrival relieves pressure on the Wanderers, whose midfield depth was to be tested this weekend with Alvaro Cejudo injured, Chris Herd suspended and Keanu Baccus away with the Australia Under-23s squad.
His signing means Western Sydney still have one free visa-player spot up their sleeve, which they are likely to use to sign a foreign winger during the January transfer window. It's understood Wanderers are in talks to sign a winger from the Spanish second division.
