The Bavarian giants take on Jurgen Klopp's men in Saturday's showpiece, and the 77-year-old believes a victory will be crucial for the Allianz Arena side
The 77-year-old, who coached both clubs throughout his career, feels the Bavarians need the cup glory more than ever before.
"For many in Bavaria, the cup has been more of a necessary evil or a consolation prize in the past. If you could not win the Bundesliga, then at least you would win this trophy," Lattek told TZ.
"However this time it's different. This time the cup is really important for the Bavarians.
"There are a whole host of reasons: they need to win the cup. They will want to avoid Dortmund doing the double. They do not want to lose for the fifth consecutive time against Dortmund.
“They must prevent the continued national rise of Dortmund. But most of all they will want to get self-confidence for the match against Chelsea," he concluded.
The DFB Pokal final between Borussia Dortmund and Bayern Munich kicks off at 20.00CET at the Olympic Stadium in Berlin.
