The 1997 Champions League winner is eagerly anticipating Saturday's final and thinks the Bundesliga champions face a tough task given their recent record against Borussia Dortmund
Bayern head into the clash at Wembley as the favourites after impressive victories against Juventus and Barcelona earlier in the competition, but Freund has warned that BVB will be up for the fight in a potentially hot-blooded encounter.
"I have a feeling it's going to be pretty physical and hot-blooded," the Tottenham assistant coach told the official Bundesliga website.
"Bayern may be the favourites, but for the most part Borussia have looked pretty good against them recently. And that will be in the back of both teams' minds.
"The pressure on Bayern is tremendous. Dortmund obviously don't want to walk off the pitch as losers, so they're under a certain amount as well, but taking the overall situation in the run-up, it's Bayern who are carrying the heavier burden of expectation.
"This is Bayern's third final in four years. Last year they were very, very unlucky to lose at home to Chelsea after being much the better side. In 2010, they were well beaten by Inter. This season, though, Bayern have impressed at every level and taking form into account they're absolutely the favourites."
Freund was part of the Dortmund squad that won the Champions League in 1996-97, when they beat Juventus 3-1 at the Olympiastadion in Munich.
