The coach is demanding a better performance than the 4-0 defeat on home turf that they suffered at the hands of Laurent Blanc's men last monthBayer Leverkusen boss Sami Hyypia has admitted he doubts his team is capable of beating Paris Saint-Germain by five goals on Wednesday.
The Bundesliga giants trail 4-0 heading into the Champions League last-16 second leg at Parc des Princes having been totally swept away by Laurent Blanc's side in the opening tie.
The former Liverpool defender accepted that PSG essentially have one foot in the last eight of the European competition but has demanded a far better performance from his players than the one which saw them crumble last month.
"I've never known such comebacks [as the one required to qualify], neither as a coach nor as a player," Hyypia told reporters. "I will not say we're going to win 4-0 or 5-0, but let's focus on delivering a good performance, both offensively and defensively.
"We will play to win, and aim to play without fear and impose our game. Of course it'll be very hard to win, but our goal is at least to deliver a good performance.
"We won't have any motivation problems: this is a Champions League game and you don't need to motivate your players.
"We have played three very high-profile matches this season in the competition, two against Manchester United and the home leg versus Paris. Each time, we played with a bit of fear, so we need to approach this match better."
Bayer Leverkusen head into the game having not won any of their last six matches in all competitions, which includes four defeats.
