After winning promotion last year, Wolves boss Mick McCarthy's funds were TREBLED and the Irishman has reaped the rewards by beating the drop against all the odds.
Jones said: "It was a fantastic achievement to win the play-offs but people forget I also had 3½ years in the top flight with Southampton.
"The Premier League is the best in the world and I want to get back there. It's the only place you want to be as a manager, coach or player.
"Wolves didn't invest then and if they had done what they have done now, maybe I'd still be there.
"But the board wanted to go down a different road and it was a bitter pill to swallow."
