Barnsley striker Kieffer Moore said snatching the title from Luton Town on Saturday would cap off an unbelievable season for the Tykes.
The South Yorkshire club were promoted on Tuesday after Portsmouth lost their game-in-hand to Peterborough, leaving Barnsley four points clear with one game remaining.
The Tykes are level on points with top-of-the-table Luton and could claim the League One title if their rivals slip up.
Moore was part of the squad who were relegated from the Championship last season. However, the striker has played his part in the team bouncing straight back with 16 goals, earning himself a place in the League One PFA Team of the Year, along with four of his teammates.
The Barnsley front-man believes the squad have enough talent to avoid another relegation from the second-tier of English football.
He said: “We’ve got a very good squad. If we keep this squad, we’ll have no worries in the Championship and prove a lot of people wrong.
“I’ve enjoyed it loads. There’s no better feeling than scoring goals and then watching the team get promotion, it’s amazing and something that will stick with me for the rest of my life”.
Moore’s teammate, Alex Mowatt, was also part of the squad relegated in the 2017/2018 season and has extra Championship experience from his time with Leeds United.
Mowatt’s contribution of eight goals and seven assists also saw him named in the PFA Team of the Year and he said the type of football played by manager Daniel Stendel suits his game.
He said: “It took me time to settle in but this season under the new manager and the way he’s got us playing really suits me.
“It’s a level up but we’ve a young team that’s been improving so I think with the team we’ve got now we can challenge the teams and do well.”
Barnsley travel to 16th placed Bristol Rovers on Saturday while Luton take on Oxford at home.
The Tykes’ match will be screened live at Oakwell for supporters unable to make the away trip.
