McCall's men travel to the Macron Stadium at the weekend to meet up with former boss Phil Parkinson for the first time since his departure from the club back in June.
Backed by over 4,300 away supporters, fourth-placed City will go into the match looking to overcome second-placed Bolton and leapfrog them in the Sky Bet League One table.
McCall said: "We were obviously disappointed not to pick up all three points against Bristol Rovers last Saturday.
"We felt that we deserved the victory but Bristol showed during the week with their win at Swindon Town that they are building a bit of momentum.
"Every game at this level brings its own challenges, and we now look forward to this Saturday which should be a great occasion.
"I'm sure our supporters respect Phil (Parkinson) enormously for the great job he did here. I totally understand why he felt that this summer was the right time for him to move on - that's football.
"I'm sure Phil will be feeling similar to myself about their start to the season. Like us, it seems they have been creating chances and perhaps feel hard done by not to have more points on the board.
"Bolton have a strong, powerful squad - a lot of good players. They certainly have the squad to challenge this season.
"They will definitely have their eyes on that top six and even trying to finish in the top two and bouncing back to the Championship at the first time of asking.
"Just like when we went to MK Dons, Millwall, Peterborough United and Gillingham, we know that this Saturday will be another tough away game.
"We sold out our allocation a while ago now, plus the fact it is a Yorkshire/Lancashire derby, there will be a great edge to the occasion this Saturday.
"I'm sure the fans we have in the ground on Saturday will make themselves heard and I hope that we can send them home back over the Pennines with a smile on their face."
