The 21-year-old winger was one of the revelations for the Wanderers in their maiden year in Australian football's top flight last term, helping them win the Premiers Plate and reach the Grand Final, where they eventually fell to a 2-0 defeat at the hands of Central Coast Mariners.
One of the first players the club unveiled as part of their inaugural squad, it appears Appiah-Kubi will now remain at the Parramatta Stadium at least until the end of the 2014/15 season after putting pen to paper to a one-year extension on his current deal.
And Western Sydney coach Tony Popovic believes the pacy attacker could go on to become a real star in the next few seasons.
"Kwabena is an outstanding prospect and a player we are very keen to continue working with and developing," he said on the club's official website.
"He's got speed, great skills and is dedicated to improving every day at training.
"We had him locked in for a second season [after this season] but as you put time and energy into a player, you need to make sure you look after your investment.
"I've said from the beginning what an exciting young player Kwabena is. He's developing well at the club and is proving every day what a good professional he is.
"I look forward to continue working with him to help turn his raw potential into strong performances on the pitch."
Having started in four of his 13 appearances last season, including in the Grand Final, Appiah-Kubi is determined to show improved displays in the coming campaign.
"It's one of the major goals I set before the start of pre-season - to get re-signed - and I was hoping for it towards the end of the season," he explained. "But it's obviously come now and Popa [Popovic] has already shown a lot of faith in me so I was very happy to re-sign.
"Being in last year's Hyundai A-League Grand Final not only gave me confidence on the pitch but it gave me confidence off the pitch, and that is what I'm trying to show now."
Appiah-Kubi was born in New Zealand to parents of Ghanaian heritage but has been living in Australia since he was a nine-year old.
