Portsmouth will move into a new £600million stadium in 2011.
Former Liverpool keeper James, said: “We want to be challenging the top four’s dominance.
“If we can break into that, the glory will be massive.
“We’ve plans for a new stadium and that design is not for a team scrapping with the likes of Sheffield United, Charlton and Wigan.
“If the team can be as good as the stadium, it will be a massive leap.”
