VIEW FROM THE DRESSING ROOM
Rotherham United manager Steve Evans tells BBC Radio Sheffield:
"We came here under difficult circumstances. We've been robbed of Michael O'Connor yesterday when he had to pull out and Rob Neilsen, he had to pull out with a back spasm.
"But Michael Tidser has come in for his first start of the season and in spells was the best player on the park, other than the boy up front [Alex Revell], who was quite exceptional.
"We knew it was going to be tough here - because we're beating them 3-0 that doesn't mean they're a bad side.
"They're a very good side and you have to work very hard to beat them."
