Wootton had a rather unconventional route to the United first team in that he hails from Birkenhead and was initially on Tranmere Rovers' books.
However, it was not long before Liverpool were showing an interest and he moved to their academy.
United always kept in touch though, and when Wootton hesitated over signing scholarship forms with the Anfield outfit, the Red Devils made their move.
"I wasn't too sure whether I was going to sign (for Liverpool)," said Wootton.
"United invited me down for a week's trial and said they wanted to sign straight after that. It was really good."
