Dele Adebola
Forest will be hoping to get back to winning ways away from home, following their 2-1 success over Sheffield Wednesday at the City Ground.
But the Sky Blues have lost only three times at the Ricoh Arena this season.
And striker Adebola warned: "Coventry do like to get the ball down when they can, but they are also a battling side.
"They are not in the position they would like to be, so it is important to them.
"They always seem to have a good home record and it is never an easy game. It is a derby of sorts and will be a tough game."
Adebola spent close to five years with Coventry, before signing for Bristol City in January 2008.
"I spent a good few years at Coventry, it will be good to see a few familiar faces," he said.
"I still know a few of the players there. It is only two years since I left.
"I am surprised to see them where they are. You can never quite put your finger on what has gone wrong there, because they started the season really well.
"They are a good side with good players and I am sure something will click for them eventually. Hopefully, that will not be tonight."
