Brighton midfielder Billy Gilmour says the players are proud after victory over Olympique Marseille.
Joao Pedro's goal saw Brighton finish the group phase as top qualifiers for the round of 16.
Gilmour said: "We've come and done it. Everyone in there is buzzing. But now we need to prepare for the weekend.
"To work with our gaffer is amazing. I'm really enjoying right now. Hopefully I can continue that [form]. I want to try to get on the ball and start stuff as much as possible.
"It's been a real joy. We've all worked really hard. Some of the results, we've felt hard done by.
"We're in the competition because we want to try to go and win it. That's the aim. We want to keep the standard in the league as well. Sometimes we haven't been at it."
