The Tigers have picked up four points from their previous two games, including a first win in 13 attempts in the league against Middlesbrough last time out, but face a Baggies side that are currently second in the Championship table and have only suffered six defeats in 40 games this season.
And while McCann knows it is a difficult task that lies ahead at the Hawthorns, he is confident that his players are up to the challenge.
“We’ve got a really tough game away at West Brom on Sunday but we can go there with confidence after getting the monkey off our back by beating Middlesbrough to end our wait for a win,” he said.
“What I saw from my team on Thursday night was a real determination to fight, to run and to work hard for one another and that really pleased me.
“It’s going to be a completely different game at The Hawthorns, but we need to show the same desire once again.
“West Brom are a very attacking side and very fluent in the way they play. They handle the ball very well in tight spaces and have numerous players that can hurt you at the top end of the pitch.
“They’ve got experience running throughout the team and are one of the best teams in the league, if not the best.
“It’s going to be tough but we gave them an excellent game in the first fixture at the KCOM and we have learnt from that. I remember Slaven Bilic telling me afterwards that it was one of the toughest games they’d had for a while.
“We know what we’re going to be in for. We’re going to have to be organised and strong defensively, but we’ve also got to carry a threat at the other end of the pitch as well.
“We’ve got to bring our attacking intent to the game. We have to go there with fire in our bellies and try and cause what many would see as an upset.
“It’s a game between two teams at different ends of the table and we have to go into it and play the game, not the occasion.”
