The 18-year-old impressed Mark Robins during a trial period, and made a move for the youngster after it was revealed he was being released by Leeds.
His release from Leeds came as somewhat of a surprise, especially after former boss Neil Redfearn praised him for his “dominance in midfield” in a recent youth academy appearance for the Whites.
But Redfearn’s departure also spelt the end for Assenso, who has now signed his first professional contract with the Iron.
Assenso was a regular in the under 18’s for Leeds last season, and will be hoping to make a good impression as Scunthorpe look to build on last season’s disappointing 16th place finish.
Scunthorpe United fans….. What do you make of this news? Will he start for you next season? Let us know your thoughts and opinions in the comments below!
