Bayern have already secured the services of Mario Gotze for a fee of £31.2 million, while they are also keeping tabs on fellow BVB stars such as Mats Hummels and Robert Lewandowski, much to the dismay of Klopp.
"Bayern want a decade of success like Barca. That's OK if you have the money because it increases the possibility of success. But it's not guaranteed," Klopp was quoted as saying by The Guardian ahead of Saturday's Champions League final.

"It could not be our way to do things like Real [Madrid] and Bayern and not think about taxes – and let the next generation pick up our problems. We need to work seriously and sensibly. We have this amount of money so we can pay that amount. But we lose players."
The 45-year-old then went on to reveal that he was close to the Bayern job in the past, but eventually missed out as they opted for Jurgen Klinsmann instead.
"Uli Hoeness [Bayern's president] asked if I would see him. I said: 'Yes sir – I have to ask my mother first but I think it will be fine.' He told me they were thinking of two coaches and I was one of them.
"Later Hoeness decided on Jurgen Klinsmann. It wasn't too disappointing – for a second division manager to be called by Bayern is not the worst thing in the world."
Klopp would eventually leave Mainz for Borussia Dortmund in the summer of 2008 and has guided them to two Bundesliga titles since.
He will be looking to add the Champions League to his trophy cabinet at the weekend when they take on Bayern at Wembley.
