The 17-year-old has already spent two weeks’ work experience at
Old Trafford, after impressing the United scouts with his
performances for the York youth team.
Middlesbrough and Tottenham are also said to be interested in the
promising forward, who is yet to make a senior start for the
Ministermen.
The Red Devils have already poached Jonathan Greening and Nick
Culkin from the KitKat Crescent in recent times, and a third deal
seems imminent.
"There were a couple of times last season when Manchester United
scouts watched our youth team as well as the other sides we were
playing," City boss Colin Walker told the York Evening
Press.
"In the end, Adam Boyes was invited on a week's experience at
Manchester United. That turned into two weeks and the second was a
tournament which he asked my permission to play in and I gave
that.
"The feedback and vibes have all been very positive but, as it
stands, Adam is still a York City player and it's been a fantastic
experience for the boy.
"It's all about an experience for the boy at the moment and
hopefully he will still be in my squad next season because you
can't buy the experience he's just had."
