While Harrison was the last in City's late flurry of deadline signings, joining fellow striker and Socceroo Jamie Maclaren in a new-look forward line, the 21-year-old will make the trip Down Under alone.

"It's just me, my girlfriend is back in England, but I'm fine at the moment," he said.

"I'll be hoping to inspire other players (to come over) as well.

"(Melbourne City) is a really, really good club. I know a bit about it and about the manager as well.

"I never imagined I'd be here, but I know the A-League is a very physical league and I'm very excited to step up and play men's football."

Harrison said Warren Joyce's English connections secured the deal, but he was excited to join a manager that he'd heard of, due to Joyce's "very good reputation" in England. 

"He has a very good reputation in England for what he accomplished with Manchester United," Harrison continued.

"It's a big test, a big difference training with the lads. Really looking forward to playing at AAMI park as well. It will be a big step for me developing as a man.

"I'm really direct and have an eye for goal, I like to get behind the striker. I think Jamie (Maclaren) and I will have a big impact. 

"As a striker, first thing on my mind is goals. I'll be looking to score as many as possible and I've only just started with Jamie but already we have a great chemistry.

"At this age, for me, it's really important that I play first team football. I'm really looking forward to this challenge, there are some great players here, like Ritchie (de Laet) and Brattsy (Luke Brattan)."
