Jack Richardson, from Ipswich, was among nearly 30,000 fans at the game.
The 19-year-old said he had seen the team go through three promotions in four years, adding that this one “feels amazing”.
“I was nervy coming into it and there was a chance we could bottle it, but as soon as I saw them two, three minutes in and we scored, it was gone,” said Richardson.
“I went out last night, got home at 3am, up at 8am and got to the pub by 9am.
“Under this manager there is no limit… it is a brilliant feeling.”
