The coach demands a better performance from his side than the 4-0 defeat that they suffered on home turf at the hands of Laurent Blanc's men in their Champions League first leg
The Bundesliga side trail 4-0 heading into the second leg of their Champions League last-16 tie at Parc des Princes, having been totally swept away by Laurent Blanc's men in the opening tie.
The former Liverpool defender accepts that PSG essentially have one foot in the last eight of the European competition but demands a far better performance from his players than the one which saw them crumble in February.
"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 PSG. Each time we played with a bit of fear so we need to approach this match better."
Leverkusen head into the game having not won any of their last six matches in all competitions, which includes four defeats.
