The 61-year-old believes the Allianz Arena side are now the team to beat in Europe and thinks Borussia Dortmund will struggle to contain them on Saturday
The Dutchman, who coached Dortmund from 2004 until 2006, feels the Bavarians' Champions League semi-final dismantling of Barcelona saw them surplant the Catalan giants as the continent's finest side, and feels Jurgen Klopp's men will struggle to contain them in Satuday's final at Wembley.
"Bayern Munich are the new benchmark in European football in my opinion," he told Voetbal International.
"It's a shame, but I don't think that we will see Barcelona's style of play again. They were able to hide their vulnerability over the years, until they were exposed when their form dropped a bit.
"Bayern's players are at an age where the current team can go on for two or three more seasons. And what's really impressive is that they have plenty of cash in the bank. They could easily spend €100 million on new players if they wanted.
"I really believed that Dortmund could win the final and that it would be 50-50. But I'm having second thoughts after last weekend. I was in Dortmund for the game against Hoffenheim and they disappointed me. They looked complacent and their defence gave away too much space.
"Bayern have length, speed, physical power, creativity and score a lot. They're like a machine that's able to use several different styles of play."
Saturday's match at Wembley kicks off at 20:45CET.
