Brendan Rodgers believes an intense atmosphere awaits at the City Ground when Leicester City head to Nottingham Forest this afternoon.
The clash will mark the first meeting between the teams in eight years but Rodgers is well aware of the opposition they will be up against.
He said he is looking forward to the occasion.
"With some of the other clubs I've been at, there have been some massive derby games, so when this came up, I was really looking forward to it," he said. "It's been a while since both clubs have played.
"I haven't been back at the City Ground since I was there with Swansea in the play-off semi-finals."
The job Steve Cooper has done with the Reds has also not gone unnoticed by the Irishman who believes will be a "tough" contest.
"It's a great stadium so it should be a brilliant atmosphere. It'll be a tough game for us because they've done very, very well. Steve's gone in there and done a brilliant job along with Alan Tate, who was a player for me at Swansea City. It's going to be a real top examination for us.
"You're going to have to perform well and we know we have to do that against Nottingham Forest because they're a good side. Steve has galvanised the team and they play mostly out of the same structure. They're very well coached, you can see that, and they've got some talented players.
"You've seen their result in the last round. It's a game we look forward to. It's a game for the supporters. We'll go there and look to attack the game and hopefully continue on our journey in the FA Cup. You can't shy away from it. You can't underplay it. It's a derby game. It's an FA Cup game."
Ahead of the encounter, the 49-year-old boss highlighted the importance of these derbies for fans.
"Playing against Nottingham Forest will always be special games for them," Rodgers continued. "We spoke about it this morning, the importance of that.
"You can't go into these games and be caught from the off. You have to be ready. I've been involved in enough derby games to understand the magnitude of them.
"[But] we're the current holders so we've got to go there and look to play football to the level we know we can play. At the same time, you have to keep that temperament. You have to keep control of that emotion to allow you to play your football, but most important for us is to play with intensity."
