Gameiro reveals Ange text
After a prolific start, Gameiro’s 2014-15 season with Sydney FC was ended prematurely in November when he suffered an anterior cruciate ligament injury.
The former Fulham striker’s form at the time had some suggesting he was an outside chance for Australia’s 2015 Asian Cup squad and it seems he was in the frame with Postecoglou.
"When I got injured I actually got a text from Ange," Gameiro revealed after City confirmed his acquisition from Sydney FC on Monday morning.
"He was nice enough to send a message, which my family and I thought was very respectful from him, because we didn’t expect to hear from him.
"It was like, 'Keep your head up. Keep moving forward. You don’t know what the future holds'.
"That was good to read when I was down in the dumps, to know at least the manager had enough thought to send me a text and I still hope to one day repay him for that."
Postecoglou monitors Australian players across the world closely but has previously admitted he rarely contacts them personally, leaving that to his support staff.
Gameiro's admission bodes well for the 22-year-old who has represented Australia at under-23 and under-20 level.
The Wollongong-born striker also revealed his road to recovery from the long-term knee injury is coming along well.
“I’m ahead of schedule at the moment. I’m doing well," Gameiro said.
“Everyone keeps saying the same thing, 'Just relax, be patient and make sure you do everything right'."
Gameiro has penned a two-year deal and will link up with his new team-mates for training at the end of June.
