Nottingham Forest manager Stuart Pearce wants his side to 'lay down a marker' against Derby County at The City Ground on Sunday.
The East Midlands rivals will clash in front of a sell-out Trentside crowd and The Reds' boss says the fans will have a crucial role to play in helping his team to victory against their near-neighbours.
Speaking to Forest Player, he said: "Any time you can sell a stadium out, you know it will be a special occasion. This game means a lot to the supporters but it also means a lot to us as well. We want to hold onto our place at the top of the table going into Sunday evening.
"It was a fixture I loved playing in as a player. Hopefully we can put a marker down against one of our big rivals for promotion and secure an important victory for ourselves and the fans.
"Two out of our three home games have been sell-outs so you cannot ask any more of the fans. I'm looking forward to the game on Sunday but even more so I'm looking forward to what will be a fantastic atmosphere."
Forest head into Sunday's clash as the Sky Bet Championship league leaders and after a two-week international break, the manager is expecting his side to pick up where they left off.
He said: "I think the break came at a good time for us. It finished off a block of matches where we stayed unbeaten and now we have to build another run going into this next block of games.
"We feel that we're in a pretty good place. The squad have a mentality which means they want to improve and want to work harder than the opposition and that really buoys me."
