Barnes has been out of club management since being sacked by Celtic in February 2000, following a humiliating Scottish Cup defeat to Inverness.
However the 45-year-old is confident of his ability, and will take inspiration from the man who gave him his big break as a player in club football, Graham Taylor.
Taylor led Watford into the English top flight against the odds in the 1980s, and Barnes is adamant it should not take piles of money to develop a successful team.
Barnes, who will reportedly be confirmed as Tranmere's new boss tomorrow, told Sky Sports News: "I'm looking forward to it immensely.
"Tranmere nearly got to the play-offs last year and I believe they can push on this year.
"I take heart from what Watford did with Graham Taylor.
"If players are committed and have desire and you have the organisation, you just have to encourage them to play and that's what I'll be doing at Tranmere.
"They were one minute away from getting into the play-offs before missing out to the eventual winners Scunthorpe, so all is not wrong at Tranmere at all."
