The former Manchester City winger has started just 18 league games during the past two campaigns and has featured only twice since Christmas.
I really hope he can make more of an impact this season," Onuoha told the Fulham Chronicle.
"It was tough for him last year from November onwards really when he didn't really get a look in, which was strange because even before I turned professional all I used to see was Shaun Wright-Phillips dominating football clubs.
"He's come back working hard and playing really well, so if he gets the chance it will be a nice boost for us which we didn't have for most of last season."
