Melbourne City sign Boca Juniors' Nicolas Colazo as their new marquee

Melbourne City have completed their squad for the A-League season ahead, having landed Argentinian winger Nicolas Colazo from Boca Juniors.

Colazo, 26, trained with City for the first time on Tuesday morning at AAMI Park ahead but won't play in the club's FFA Cup quarterfinal against the Western Sydney Wanderers on Wednesday night.

City have yet to complete the paperwork surrounding the left-sided player's marquee move from Boca Juniors, which wraps up coach John van 't Schip's offseason shopping.

"We are finished with our signings, which I am very happy with. We go forward," the Dutchman said.

Colazo landed in Melbourne on Monday and is aiming to play in Round One of the A-League.

"He had the opportunity and liked the opportunity to join us in this project. We're happy," Van 't Schip said.

"He's a player that can play up front, midfield and even in defence ... technically strong and a good left foot."

Colazo joins countryman Fernando Brandan, Socceroos great Tim Cahill, Danish international Michael Jakobsen and home-grown talents Bruce Kamau, Luke Brattan and Neil Kilkenny as City's major signings.

And Van 't Schip says the rest will all be in the frame to face the Wanderers, a match he labelled as "a great test."

"It's very important to see where we are only a few weeks before the A-League starts," he said.

"It's a cup game and we want to win."

Local fans should see Cahill and Jakobsen in home debuts, but Van 't Schip was coy on whether they would start, particularly given Cahill's success as a Socceroos super-sub against the United Arab Emirates a fortnight ago.

"He had a big impact in the short time he came on," he said.

"[Cahill] looks good, he feels good and he's ready to play.

"[Jakobsen's] in a good condition because he came out of a league playing in Norway.

"He's a player we want to have normally in the starting line-up.

"He has a very good pedigree, a good defender, a good age. We expect a lot from him."

Against the Wanderers, City are coming off back-to-back friendly beltings to Wellington and Newcastle.

In a 4-1 loss to the Phoenix, the coach blamed a heavy training load in Sunday's 4-0 loss to the Jets, Van 't Schip fielded a youth side.

The biggest loss of the last fortnight, however, was Corey Gameiro, who ruptured an ACL for the third time in as many years while training in Townsville.

"It's very disappointing," he sad.

"For him the most. It's tough. It's mentally very hard.

"We're trying to do what we can to support him."
