With their domestic cup hopes ended and the Premier League title defence long since over, the Champions League represents Liverpool's final opportunity to secure a trophy this season.
Wirtz believes that the team must find a new level of consistency to overcome the reigning European champions, PSG, across two legs. He emphasised that anything less than a perfect 90-minute performance in Paris would leave them with "no chance."
"We believe in ourselves, we have a good group with good characters and great players, also a good manager who tries to prepare us good for the game," Wirtz added.
He also suggested that having the second leg at Anfield could prove to be a decisive advantage for the Reds.
