Florian Wirtz has dismissed suggestions Liverpool's players have lost faith in Arne Slot - but disagreed with captain Virgil van Dijk that they downed tools against Manchester City at the weekend.
And the Germany international has warned the Reds will have "no chance" of beating Paris Saint-Germain unless they produce a 90-minute performance in the Parc des Princes on Wednesday evening.
Liverpool arrived in France on Tuesday ahead of their Champions League first leg against the holders, still smarting from the dreadful 4-0 FA Cup quarter-final loss at Manchester City at the weekend.
It placed further pressure on beleaguered Reds boss Slot after a dismal defence of the Premier League title won in dominant fashion last season that has left Liverpool in danger of missing out on Champions League qualification altogether.
But when asked if the squad is still playing for the Dutchman, Wirtz said: "Yes, of course. We are believing in the manager, the team should believe in the manager as they won the league last season, we have had a lot of good games this season.
"We wanted it to be better but it is what it is now. We still have things to play for and everything I can say to that is that we believe in the manager and will try to get our best on the pitch tomorrow.
"We had some goals this season, the team won the Premier League last season and it was for sure the aim for this season as well.
"We are still in the Champions League now so we still have something to play for and qualification for the Champions League next season.
"We have shown this season already we are good in big games, especially in Champions League. We believe in ourselves, we have a good group together with great characters and players and a good manager who tries to prepare us good for the game."
Van Dijk reacted to Saturday's FA Cup loss by stating Liverpool at one point gave up during the match with City having scored four goals inside 20 minutes either side of half-time.
But while agreeing with the skipper's call for unity, Wirtz, speaking inside the bowels of the Parc des Princes to the assembled media on Tuesday evening, fell short of concurring with the assessment the Reds stopped trying.
"I didn't know he said this," said the 22-year-old. "But I think I wouldn't agree directly because we still tried to create chances to turn the game around.
"We have to stick together in the bad moments. The weekend we tried too much at one point and were a little bit wild on the pitch, we have to fix that for the next game.
"Of course when the game gets longer and it's like in the 80th minute and you're 3-0 back, mentally it's difficult to go and go. We just tried to give our best in the game, and when it was 3-0 or 4-0 we had still a few chances then. But it's not our standards that we lose 4-0 against City."
Liverpool come up against a PSG side which hammered Chelsea 8-2 on aggregate in the last round and are on course for a fifth successive Ligue Un title.
And Wirtz said: "We need tomorrow 90 minutes full energy and full commitment, otherwise we will have no chance.
"We need 90 minutes of being together as a team, also in difficult moments if we concede we have to stick together and believe that we can win this game and also hope that everything is that we still have a second game at home.
"We will give everything tomorrow. We have to give in both games everything we have. We can't think everything will go well at Anfield. We need 90 minutes in both game with full focus.
"We know the second game at home is maybe an advantage so we try to do our best, believe in ourselves and come first of all with a good result to Anfield."
Wirtz has found it easier to impress in the Champions League this campaign following his £116million move from Bayer Leverkusen last summer and is poised to make a first appearance in the quarter-finals of the competition.
"These are the games you want to play as a player and I dreamt of when I came to this club," he said. "We had a few good games in the league as well, but maybe it shows the Premier League is a tough league and anyone can beat anyone.
"Champions League nights are always a bit different, you meet different clubs from different countries with different playing styles. Until now we've enjoyed it. We are just looking forward to facing PSG tomorrow."
