The talented teenager will have to find another pathway for his career.
Leeds United announced their retained list for next season yesterday, with the likes of Alex Cairns, Aidy White and Rudolph Austin all being sent on their way.
The likes of Kalvin Phillips and Lewis Walters were, as expected, retained but other young talents were not so lucky.
One name that popped up was Isaac Assenso, which will certainly come as a surprise to some.
The midfielder, who recently had a trial at Scunthorpe United, has clearly not done enough to earn permanent terms at Elland Road.
However, at the start of the season, current head coach Neil Redfearn was high in his praise for the combative midfielder - who can also play at the back.
He told the club's official website in August last year, after Assenso had starred in a youth game against Ipswich Town:
"Isaac Assenso, who was a second half substitute, was our best player and his dominance in midfield went a long way to our good second half display."
At the time Redfearn was the Academy Manager and Head of Coaching at Leeds, before making his way to the top job after both Dave Hockaday and Darko Milanic were both relieved of their duties.
However Assenso must not have developed over the season in the way Leeds would have liked.
Here's hoping he can have a successful career wherever he ends up playing next.
