For an 18-year-old, Mells has had an incredible start to this football career. And there's so much more to come from him, you'd expect.
Mells was spotted – and signed – by English Premier League giant Chelsea at just 12 years of age before moving onto Southampton’s youth set-up a couple of years after.
What an incredible opportunity that must have been for the youngster and it’s given him a great football base to forge his career.
While things didn't work out abroad, it's been a blessing for Adelaide and Hyundai A-League fans.
In search of some first-team football, Mells decided to return to Australia and the A-League this season and has already made a good impression with the Reds.
He’s made three starts in his eight appearances this season, even relegating Marcelo Carrusca to the bench.
Mells, who has played youth international football for both Australia and Greece (at under-17 level), has created four chances this season and made eight crosses from open play.
Look for Mells, originally from Melbourne, to play more of a role with the Reds as the season goes on as the club look to make a charge up the Hyundai A-League ladder.
It’s why he’s one youngster to keep an eye on in the race for the NAB Young Footballer of the Year award this season.
