We know all too well just how dangerous Brighton & Hove Albion can be.
The Seagulls picked up their first-ever away win against us back in December, with Neal Maupay heading home a late winner at Emirates Stadium.
And Mikel Arteta says his side can't afford any complacency against Graham Potter's resurgent side.
"I think he's changed completely the way Brighton plays," our head coach said. "He sounds very convincing and I think the players are buying into what he's doing as well.
"They are a threat, they showed at the Emirates that if you're not at it on the day, they're going to create a lot of issues. We better be ready because it's going to be a really tough game for us.
"I think to talk about advantages [of having the experience of a behind-closed-doors game] now is not very important," Arteta added. "We are all adapting. The experience from last night is very strange.
"From the moment you travel, how you get to the stadium, the feelings you have during the warm-up, during the game, it's completely different. We are all adapting. We experienced yesterday and we can talk about things that are needed to raise the level of motivation as well, and sustain that but I don't think it's going to be a big issue."
