The Anglo-Nigeria netted a sublime away goal to help the Cottagers keep their English top-flight promotion hopes alive
The 23-year-old’s strike and an effort from the Democratic Republic of the Congo international Neeskens Kebano gave the Cottagers a 2-0 advantage ahead of the second leg on Thursday.

Onomah is delighted with his strike in the encounter and praised Fulham boss Parker for giving him the opportunity to showcase his ability.
“Harrison Reed gave it to me and when I got into the box I knew they couldn’t really touch me so I triple-pass them and when I hit the back of the net I was over the moon,” Onomah told FFCtv.
“It was a great feeling for men and my family, we will go into the second leg and do the same again. I relaxed, stayed calm and gained composure and did that and got the reward for it.
“He [Parker] is someone I looked up to, I dedicate that goal to him because he someone who always believes in me and I thank him for giving me the chance.
“From the day one I have come in he has always believed in my ability trying to get the best from me and towards the end of the season, I started to show him.
