"Now we go to Millwall which will be a bit more like Sunderland in terms of a big, big game away from home," he says.
"We need a different side to our game.
"You have to draw on all sides of your character in this division.
"There are never two games the same and certainly this is a very different one to Crewe."
Looking back on that 4-2 win, he says:
"We played some fantastic stuff, and I don't want to say any negatives about the game, because it was a potential banana skin for us which we dealt with very well."
He feels it was the perfect response to the 2-0 defeat at Sunderland last weekend, and adds:
"We were disappointed with our performance against Sunderland as a whole team unit and we wanted to put that right.
"The only way you can do that is go into the next game in the right manner, which we have done.
"You can't turn the clock back."
