After putting pen to paper on a two-year deal on Monday, McCall was officially unveiled as Bradford City manager for a second time at a press conference this Tuesday.
Speaking in front of the assembled media, McCall revealed his desire to get started again at the Bantams after being won over by the ambitions and structure of the club.
Having managed City once before for three years between 2007 and 2010, McCall feels he is a much more experienced coach now and ready to keep the momentum going at the club following last season's Play-Off finish.
McCall said: "I'm looking forward to an exciting challenge.
"This is a fantastic opportunity. I was looking to get back into day-to-day management but I wanted to find a club that had a good fan-base, a good structure and a club that matched my own ambitions.
"This decision to come back has not been led by emotion. I've looked at the infrastructure of this club and I know it can go places - I have a desire and a determination to be successful.
"The two owners are enthusiastic and energetic, and my meetings with them have very positive. We all want to keep the good work going from recent years.
"They have positive ambitions for this club and so do I.
"The club is completely different to when I first came here (as manager) nine years ago and I am a different manager now.
"I have worked in the Champions League, the Europa League, internationals and cup finals since my last spell here. I am a lot more street-wise now, a lot more experienced and equipped.
"Something that will never change with me, however, is my desire, my energy and my positivity.
"The club has been moving in the right direction in the last few years and we don't want that to stop.
"I can't wait to get going and to meet the players. I've been to the training ground this (Tuesday) morning and it is night and day compared when I was last here.
"The structure is here, the fan-base, of course, is here. I went to a few games last season and the atmosphere was tremendous.
"We just have to build on all of that now and be positive.
"The fans truly are like our twelfth man here and we want to give them the football that will get them excited."
Fresh from rejoining the club, McCall says work has already begun to strengthen the squad.
The City chief says he is eager to bring in new additions as soon as possible but McCall was also keen to stress that any players brought in must be the right ones.
McCall added: "It isn't a big squad at the moment but we inherit a dressing room with good players in it.
"The loan market is going to be important as well. A lot of teams, including Barnsley last season, have used it to their advantage in this division.
"This area could be key, especially with the short-term loans ending this season.
"We are trying to recruit players as soon as we can. Whether it be big signings, young players or loan signings though, it is a case of getting together the right blend and the best squad possible.
"I've done that in the past and I look forward to doing it again.
"We are looking to improve the squad in all areas.
"We know there is a hole in midfield after the two lads (Lee Evans and Josh Cullen) went back on loan but we are trying to improve all areas of the squad.
"As Edin (Rahic, joint-chairman) said to me, we are not after the players who are available, we are after those who are good."
With a number of staff members joining up with former manager Phil Parkinson following his move to Bolton Wanderers earlier this month, McCall, who will be assisted by number two, Kenny Black, says City will look to add to their coaching staff in the coming weeks.
McCall said: "It is an area we are looking into. We'll need a goalkeeping coach, a scout and someone for fitness.
"Discussions are on-going with the chairmen and it is something we are looking to resolve.
"I have already brought Kenny in and he is a workaholic."
Prior to his appointment at Valley Parade, McCall had been working with the Scottish national side.
The 52 year-old has revealed, however, that he has ended his association with Scotland to focus on his new role with the Bantams.
Speaking about his Scotland role, McCall confirmed: "No, I can't continue with that.
"I've had three fantastic seasons up there - I learned a lot under Gordon Strachan and working with some brilliant players - but I can't keep going with our games being on at the same time as the internationals.
"I rejected a couple offers over the last eighteen months because it would have meant leaving Scotland but I couldn't turn this job down."
