Oboavwoduo’s crucial contribution took his tally for the season to 18 goals - the joint-highest return of any forward at U18 Premier League level.

Speaking to Matchday Live’s Mike Minay after the match, he said: “It’s great playing in this stadium.
“I’ve dreamt of it since I being here when I was six.
“I dreamt of being here when I was a ball boy as a little kid, so to be able to play here and to score two goals was unbelievable.
“Hopefully [I will play here] many more times in the future.”
