Owen Coyle was unveiled as Bolton manager on Monday morning and described moving to the Reebok Stadium from Burnley as an "unbelievable wrench" but also an "exciting challenge".
The former Wanderers striker was on the verge of succeeding Gary Megson all last week and was officially announced as the club's new manager on Friday evening.
At his opening press conference as Bolton boss, the 43-year-old insisted he understood Clarets' fans disappointment at his decision to move on, but maintained his departure was inevitable at some point.
"We know in football there's two things which happen to football managers: you do well and you move on or you don't and you're moved on," said Coyle. "I think that's what's happened.
"It's very emotional, but it's such an exciting challenge here and that's what we have to look forward to."
Coyle's arrival was confirmed after protracted negotiations with the Clarets, who he led to promotion from the Coca-Cola Championship last season.
The decision to move on was not straightforward, Coyle insisted.
"It was difficult," he said. "The emotional attachment alone over the course of two years... but when all was said and done we tried to take the emotion out of it and make what we felt was a football decision.
"I understand totally the sense of hurt and disappointment the Burnley fans would feel.
"It's a natural reaction and I think it can't be lost on anybody what we did do over two years.
"When I came into the football club we were in the bottom half of the Championship.
"We pulled it all together and that's probably why I'm here.
"The job we did do catches other peoples' eye."
Coyle insists his decision to turn down Celtic in the summer is proof he has not made the move to secure a bigger salary.
"I've never been motivated by money in my life," he said. "If it was finance I would have taken the job at Celtic in the summer. That is just a knee-jerk reaction from people that do not know me.
"I have an unbelievable challenge ahead here at this magnificent club, with a magnificent stadium, and I have to take that on.
"You want to be the best you can be and that's my motivation. I want to be involved at the highest level and the highest level in world football is the Premier League.
"There's no doubt about it, the best individual players in world football operate in the Premier League. You want to go and compete with the best in the business.
"Celtic were the team I supported as a boy and I spoke with Celtic in the summer. They offered me the job and I turned it down to stay at Burnley. I think that puts to bed anything about finances."
Coyle added: "If you look at the infrastructure of the club (Bolton), the academy, the training centre, everything is geared for top flight football and my job as manager is to make sure that happens.
"I must say, Burnley have still got a Premier League team as well. We really galvanised the club and took them to a level that is always going to be difficult.
"On balance I had to look at if we'd achieved survival, come the summer is there going to be that investment? I wasn't sure there was. In a transitional period I was trying to move things along quicker than finances would dictate."
Coyle hopes the Trotters fans will eventually get behind the team.
He said: "My message is the same as it always is to football supporters; come and support your football team. I'd say to Bolton fans come and support your team and get behind the lads.
Asked about his plans in the current transfer window, Coyle said: "First and foremost I have to be fair to the current squad. I've always felt the January window can be a an inflated market anyway so we'll have to look at that.
"If something is there that I think can improve the football club then it's something we'll look at."
