Defeat at the home of The Rams who are also just above the relegation zone could see the Sky Blues further if results were to go against them over the weekend whilst a victory would give a bit of breathing space.
“People often talk about must-win games and I think it is a little early in the day to say that for both teams but maybe it is in terms of the fact that we have been on a bad run,” Chris Coleman said to the CT.
“It is an important game for us and chance to put right what we did wrong last week but they will be thinking the same way.
"You never get a defeat out of your system until you win your next game, so that’s not gone yet.”
Kick off is at 7.45pm and if you are not going to Pride Park, the game is live on Sky TV.
