The rivalry between the two clubs is relatively unknown or underplayed outside of the bubbles of Palace and Brighton, but to those involved, it is incredibly fierce and hostile.
Heading into the clash at the Amex, Eagles boss Glasner completely understands the significance of the rivalry, putting aside external noise.
“One of the funniest things about emotions is very often the guys who are not involved don’t understand,” said Glasner.
“It’s about you and me; we are involved, we know what happens. It doesn’t matter if the fans of Manchester City or United understand the rivalry between Brighton and Crystal Palace because they have other worries and not this.
“It’s important what our fans are feeling, it’s important what the club feel, it’s important what we are all feeling.
“We feel that we have to do everything to win this game. This is how we enter it. This is how we will play.”
However, the Palace boss stressed that his side must not allow emotions to interfere with the on-field performance on Sunday.
“We were not talking about the rivalry during the week because we are working on patterns and what we want to do. We are not working on the emotions.
“On Sunday, we will work with the emotions. To be in the right mood and have the right motivation and attitude for the game. But until Sunday, it’s about preparing the best way. We have what we need.
“Also, this week is where we can get a football impact, physical impact, tactical impact and technical impact. Next week is just recovery, playing, recovery, playing, recovery.
“We tried to use this week to have this impact, this input to the players and not about the emotions.
“We didn’t talk about the rivalry until now, but again, we will have enough time. We had a meeting on Saturday morning; we will have a meeting on Sunday morning in Brighton. So, enough time to get the right setup.
“But we are entering the game the same way we did Man City and the same way we will Arsenal because, for us, it’s important not to show emotions in the preparation.
“We should show the emotion on Sunday evening. Before the game, it has to be more analytical. When the game comes closer, then maybe we press the emotion button.
But during the week, it was about how we want to play, how we can improve, how we can create more chances, how you can give fewer chances away. Also, we had to make a few adjustments to play against Brighton with their pace in attack.
“You can’t start with the emotions on Tuesday and keep it on the top level until Sunday afternoon. Sunday morning is early enough.”
