City strengthen with Gameiro addition
Gameiro, 22, was released by the Sky Blues at the end of the 2014-15 season after two injury-affected campaigns.
He becomes City's third signing, joining Socceroos full-back Ivan Franjic and teenage attacker Steve Kuzmanovski.
City coach John van 't Schip was delighted with the signing of Gameiro, who has scored five A-League goals in his career.
"We have been monitoring Corey's progress and believe he has huge potential with us at Melbourne City FC," Van 't Schip said.
"Corey has proven he has what it takes to be a successful striker in the A-League, showing that he has the desire, skill and hunger to succeed.
“He is a great professional and is excited about his move to Melbourne and we are looking forward to welcoming him to the club.”
Gameiro is still recovering from a ruptured ACL, but is happy to be joining City.
“I’m ahead of schedule at the moment, so I am doing well,” he said.
"The facilities here are excellent and I am very happy to be here at the club and continuing my rehabilitation in the Academy’s fantastic gym.
“I believe the club is heading in the right direction, have the foundations right and have the potential now to achieve success and I want to be a part of it."
