Melbourne City captain Patrick Kisnorbo believes his A-League side can upset their English Premier League sister club when they meet Manchester City on Saturday night.
Melbourne City were brought under the City umbrella last year when the Abu Dhabi-based owners took control of then A-League club Melbourne Heart.
The two Cities face each other on Saturday night for the first time, and Kisnorbo says in pre-season, the opportunity for a boilover is there.
"Anything's possible," the centre-back said.
"It's early in the season, we're getting to know each other on the pitch.
"Like any other team we're going to try our best and whatever happens, happens."
Kisnorbo said his side's focus would be spending time together both on and off the pitch to try and gel several new signings.
Coach John van 't Schip has added Ivan Franjic, Corey Gameiro, Michael Zullo, Steve Kuzmanovski and Aaron Hughes to his squad, and made Harry Novillo's trial move permanent in a busy off-season.
Restrictions around Manchester City's participation in the International Champions Cup next week on the MCG has moved their match to the Gold Coast.
But Kisnorbo said travelling together only added to the benefits from the one-off match.
"It's a great experience to get away, spend some time with the players and get some good team bonding," he said.
"We'll train well, train hard and play against one of the best teams in the world, with world-class players.
"With that opportunity we can take some pointers and see where we are at for the season ahead."
Despite having the same owners and close off-field ties, the clubs won't train together, preferring to concentrate on their respective seasons ahead.
But the two teams are staying at the same hotels and are likely to share meals, deepening personal relationship between the sister sides.
