The Robins will be led by interim head coach Dean Holden for the first time after the departure of Lee Johnson at the weekend, who was relieved of his role following a fourth-consecutive loss at home to Cardiff City at the weekend.
Despite being winless since the campaign restarted, Bristol City can still mathematically claim a top-six finish and McCann is expecting a tough encounter as his side go in search of a return to winning ways at the first time of asking.
“It’s a new man in charge at Bristol City now following Lee Johnson’s departure last week and we have to expect the unexpected,” he said. “We’re going to be a wee bit in the dark in terms of knowing how they’re going to play.
“When a new man comes in, they may want to put their own stamp on it and maybe change a few things or change everything. We’ll just have to wait and see.
“It’s potentially going to change the dynamic of the game but, ultimately, our focus is on ourselves as I always say. We have to focus on our own performance and what we have to do.
“If we play like we did at West Brom and show the same grit and determination we showed against Middlesbrough then I’m confident we can go there and get a result.
“We know it’s going to be tough but each game is another opportunity and we’re determined to go there and produce a positive performance that can help us pick up would be an important three points in our bid to stay in this division.”
