Liverpool go to Falmer stadium for today's early kickoff sitting in fifth place, two points outside the top four.
Wirtz told liverpoolfc.com: "Yes, it will be very important for us, also for our mind and also for the spirit in the team that we just create momentum and also an energy that we can win all the games now.
“It’s always good to have a better feeling and also a better atmosphere in the changing room because when you don’t win the team is not really happy.
“So, it’s always better to win and of course we need the points as well so we will be ready for the game and try to take the three points home.”
Of his own current form, the Germany international added: “It was a bit annoying with my back because it first was away, then came back again. But now I am fine, I feel good and I’m happy that I can keep on going where I stopped before the injury.
“These stats are nice, always good to know and to speak about. But, for me, always the most important thing is that the team does good. But when I can help like this, to create chances to score, then I’m happy."
