OXFORD United’s youngsters delivered in style with a classy victory at Wycombe Wanderers which sent them through as group winners in the Checkatrade Trophy.

Cameron Brannagan, Marcus Browne and Sam Smith were on target to secure a 3-0 win which if anything flattered the hosts.

It saw them leapfrog the Chairboys, who were eliminated, to earn a home tie in the last-32 next month.

United made seven changes and boss Karl Robinson was thrilled to see such a youthful line-up deliver.

He said: “In the 18-man squad we think the average age was 20.1. To have that is unbelievable.

“The team showed the same type of appetite from the players who have been playing, so you’ve seen a consistency in the performance, regardless of the changes we made.

“The front three were unplayable, the three in midfield had energy to burn – they were a joy to watch – and the back four were put together and kept a clean sheet.

“We got our young players on and we’re happy with our evening’s work.”

Robinson named five teenagers among his substitutes and handed two their senior debuts in the second half.

For midfielder Aaron Heap it continued a fantastic week, following a second call-up for Northern Ireland Under 19s.

But for the boy from Bletchingdon, who has been at United for a decade, cherished the chance to come on for his local team.

He said: “It means the world, especially as I’ve been here for ten years.

“It’s incredible, the best feeling ever, I’ve dreamed of this for so long and now it’s actually happened. I’m buzzing.”

The other debutant was striker Harvey Bradbury, whose family were in the away end.

They included father Lee, who spent two years with the U’s in a career which included spells at Manchester City and Portsmouth.

The pair are the first father and son to play for the club since 1949 and the youngster was delighted to get the opportunity to make his own name.

He said: “He (Lee) was sat behind the goal with my mum and my sister.

“It’s good to play for the same club.

“It is tough, but he doesn’t put any pressure on me.

“I always get ‘you’re only here because of your dad’ growing up, so it’s good to make my debut and hopefully shut those people up.

“Coming in the dressing room earlier on and seeing my name on the back of my shirt I thought ‘this is what I’ve dreamed of my whole life’.

“And to get out there on the pitch, it was brilliant.”
