Hannover 96 coach Mirko Slomka believes his side need four wins from their remaining wins to reach the Champions League.
Die Roten currently occupy the third and final qualifying berth for a place among Europe’s elite clubs next season, but they hold only a one-point lead over fourth-placed Bayern Munich.
And having leapfrogged Munich last weekend, Slomka admits they can only afford one more slip-up if they are to finish in the Bundesliga’s top three.
Speaking ahead of today’s trip to Hamburg, he said: “Four wins from five games should be enough.
“But we are going to have to be stable for 90 minutes, not 30 like in Cologne or 60 like in Dortmund, otherwise we can forget about the Champions League.
“It is going to be a very tough game.”
While Hannover 96 head into this game on the back of a 2-0 win over Hannover 96, Hamburg will be looking to build on a 1-1 draw with leaders Borussia Dortmund that took their unbeaten run to three games.
