The Scot says the home fans will be key.
"There's big expectations when we play at home," he told the Birmingham Mail. "No one wants to turn up and play bad, it's been difficult the last few seasons and I understand the frustrations.
"Again, we're working to try and fix that and be positive.
"The fans have been loyal, unbelievable.
"They pack out grounds away from home all the time, I look back at Burnley and Palace recently and remember that they've been brilliant.
"They can help you so much. People don't realise that."
