Nicolas Colazo has signed for Melbourne City for the upcoming season, rounding out City's 2016-17 A-League roster.

The Argentine joins City as a marquee player alongside Bruno Fornaroli, with Tim Cahill taking up the new guest marquee spot.

Colazo has been a key member of Boca Juniors' squad since making his first-team debut with them back in 2009, making 148 appearances for the Argentine giants.

The 26-year-old won't feature in City's FFA Cup quarter-final clash with Western Sydney on Wednesday night, although head coach John van't Schip is hoping Colazo will be available for their opening league tie against the Wellington Phoenix.

“That's something that we have to have a bit of a better look at. He's been training the last few months with Boca and has played some internal games,'' van't Schip said.

“He's in a good physical state we just have to work out if he's match fit.

“We like him, he's a good player, he played on a high level in Argentina with Boca, who's the biggest club there along with River Plate.

“He's been a big part of that team. He had some issues and therefore didn't play too much last period.

“He liked the opportunity to join us in this project and we're happy that we can hopefully let him in, I don't think it'll be a problem.

“He can play up front, midfield and defence so he's versatile, technically strong and a good left foot.''
