"If I was keeping everything within me and not letting it out,it's going to come out[later],and where else is it better to come out than here? Because then we can solve it,"he said.
That sort of close-knit treatment,Mabil believes,is typical of Midtjylland,a young club on the rise in European football. Founded in 1999,what they lack in stature and resources they make up for through culture and ingenuity.
Once nicknamed'FC Moneyball',Midtjylland has used data analysis and statistics to step out of the shadows of their cashed-up rivals and pounce on the hidden opportunities they might miss.
Mabil is emblematic of their approach. When they signed him from Adelaide United in 2015 he was the rawest of talents - a skinny African kid with a bag of tricks but little consistency or composure. But having carefully nurtured him over the past five years,late bloomer Mabil is now a mainstay of their team and a powerful,dynamic presence on the wing. He was pivotal in their 4-1 aggregate win last month over Slavia Prague,which sealed their maiden Champions League qualification.
"This club will have a special place in my heart always,because I became a man here,"he said."When I first came here I was a young boy from Australia,dreaming big,thinking I'd come to Europe and I'd just play. Then I got a reality check,but they allowed me to grow here ... many[other] European teams,they wouldn't do that. They would just kick you out."
Midtjylland has been drawn in Group D alongside Liverpool,Italian outfit Atalanta and Dutch giants Ajax,who once had Mabil on trial before he signed for the Danish club. It's a tough pool on paper but Mabil can see a way through it.
"For us now we have nothing to lose,no-one is expecting us to do anything,"he said."But we know how dangerous we are. If anyone switches off we're going to punish them - that's our mentality."
Like many football-mad Aussies,Mabil has fond memories of getting up early before school to catch his favourite team,Manchester United,taking on the best of Europe.
"I always used to trick my mum,"Mabil said."When she would go to work,she'd tell me to go to school. I'd go hide and then she would drive off and I would come back inside and finish the second half and then go to school - and then fake an autograph,saying'Awer is late because of this'and then sign it with my mum's autograph."
Mabil is the only Australian in this year's Champions League tournament - only a handful of his current Socceroos teammates,like Milos Degenek,Trent Sainsbury and Aziz Behich,have played in it before.
But at a time when the number of Aussies plying their trades at top European clubs is drying up,Mabil believes his responsibility goes way beyond just doing what he can to help Midtjylland win games.
It's to be a beacon of hope for anyone who's been through tough times - as well as the kids with stars in their eyes back home who set their alarm clocks at an ungodly hour,and might even wag school like he did to catch the whole 90 minutes.
Other players might shirk role-model status and focus on themselves.Mabil sees it as his calling.

"It feels like I'm representing my country,even though I'm playing for my club,"he said.
"It doesn't matter if you're from Australia - we can be playing at the highest level of football. We've been to the last three or four World Cups. Why can't we have a lot of players in the Champions League?
"The last seven months I found my happiness again. And I know now I only have one job,and that's to try to set a way - a path for the next[ones] to follow. I think that's my job,just to show people that no matter what you go through,you can still overcome things. That's my purpose now."
