Owen Coyle has said he rejected "seven or eight opportunities" before agreeing to become the new Wigan manager.
Coyle, 46, was sacked by Bolton in October, five months after they dropped into the Championship under him.
"I felt it was important that I did not take a job for the sake of taking it. It was important I took the right job, which I feel Wigan is," he said.
He succeeds Roberto Martinez, who joined Everton after the Latics were relegated from the Premier League.
That ended an eight-year stay in the top flight, with chairman Dave Whelan telling BBC Radio 5 live last week that "returning to the Premier League is the total and utter priority".
Coyle has taken control of a much-changed squad, with Hull-bound defender Maynor Figueroa one of several players coming out of contract and loanees like Atletico Madrid goalkeeper Joel Robles returning to their parent clubs.
His squad could be further depleted by sales, with midfielder James McCarthy the latest to be linked with an exit.
Coyle accepted the situation, but went on to reveal he had been assured that any money generated from sales would be "reinvested".
"In regards to numbers, we must add some," the former Republic of Ireland international said.
"We accept there are some hugely talented players left here, who will be coveted by other clubs. The chairman has shown through the years that he will not stand in any player's way if it is the right deal for the club.
"What I do know is that any money will be reinvested into the club, which for a manager, is a huge thing to hear."
Despite looking to bring in players, the Glasgow-born manager distanced himself from Kevin Davies, who was Coyle's captain at Bolton and is a free agent.
"Kevin was my skipper and an outstanding player," he said.
"I think there is a bit of interest in Kevin but it is probably not what we are looking to bring into the football club, although he is an outstanding man."
