Bremen coach Thomas Schaaf's near 14-year reign as coach could be riding on the outcome of Saturday's match, but Hyypia insists that is none of his business.
"Bremen have not had the season they would have hoped for, but they are certainly better than their league position," he said.
"We have got to focus on ourselves only and go into the game full of self-confidence.
"We still have four games to go and have not achieved anything yet."
Indeed, Leverkusen are still potentially two wins short of securing their place in the Champions League next season, although should results elsewhere go their way this weekend, they can celebrate reaching that goal with three games to spare.
Victory for Bremen could all but mathematically see them safe from relegation, yet that would still not be cause for celebration.
Schaaf has been keeping a low profile this week and hopes his team can do the talking for him on Saturday.
"We have been very focused on our jobs and searched for the key there," he said at the pre-match press conference.
"We can only change our situation on the field and the foundations for that need to be laid in training, and we have worked on that intensely."
A little too intensely, it could be claimed, since Kevin de Bruyne is set to miss out on Saturday.
"I took two knocks on my right thigh and it was the same place each time, and it is very painful," said the Belgian.
Omer Toprak returns from suspension for Leverkusen and should start.
