Rotherham United manager Paul Warne told BBC Radio Sheffield:
"To win 4-0 at home flattered us. They had a sending-off. You can take some confidence from that, but the game was so long ago it does not really have the same effect.
"When we got done at home by Oxford and took a good licking, even though the scoreline doesn't suggest that, there were was a real determination to right the wrong, which we did. And I'm sure Coventry will feel the same, so we have to guard against that.
"What has helped them this season was at Coventry they played on a rugby pitch and it can be difficult to play the way you want on a surface like that but, at St Andrew's, the pitch is always beautiful to play on and it has suited them. If they haven't got the best home record in the division, but it's got to be up there.
"I'd be lying if I said it was just another game. We go into the last quarter of the season in good health. It should be a good spectacle and one that both teams want to win."
