After returning to pre-season training last week, McCall's men will kick things up a notch at Guiseley's Nethermoor ground this Saturday afternoon (3:00pm) with their first friendly encounter ahead of the forthcoming 2016/2017 campaign.
For McCall, it will be his maiden match in charge of City following his appointment as manager of the Bantams for the second time last month.
As with most opening friendlies, McCall says that the plan is to play two largely separate teams during the Guiseley game - one per half - with a mixture of City's first team, youth team and trialists making up the sides.
McCall said: "I went to see Guiseley and Huddersfield Town the other night (Wednesday) and Huddersfield made a full eleven changes at half time. We will probably be doing the same.
"In your first game back you only really want the lads to be playing 45 minutes.
"We will be using some of the young lads and some of the trialists we've been looking at in training recently to give us some extra options.
"Saturday's match isn't really about the result, it is more about getting our principles and our style of play across to the players and the lads themselves getting a good work-out.
"We will look to give the players a 45-minute run-out and then move it up from there as the matches go by in pre-season.
"Guiseley gave Huddersfield a good game when I saw them so it will be a competitive match on Saturday. Our players will be looking to make an impression on the staff and we're looking forward to it."
Filipe Morais had spent the early days of pre-season restricted to gym work as City erred on the side of caution due a sore knee but the Portuguese winger was back out training with the rest of the squad on Thursday.
McCall added: "He's been desperate to get out on the training pitch but we didn't want to rush anything. He had a little bit of tendinitis in his other knee, not the one he damaged before, but he's been looked after and he's raring to go now.
"James (Hanson) had a little gash in his calf at the end of last season which became a tear when he tried to play with it. But everything is fine now and he too is also raring to go again.
"Nathaniel (Knight-Percival) had a minor cartilage operation at the end of last season so he is understandably a little behind the rest of the lads in terms of his fitness but he has already shown us his quality on the pitch.
"It is just unfortunate that Rory (McArdle) and Stephen (Darby) have injuries and will be out for the early part of the season."
