The Germany international told Munich's Tz that all will become clear after next Sunday's final, which he hopes to be part of.
"I've read all the reports - it's hard not to - but I've already said that nothing is decided yet," Kroos said.
"The latest reports simply weren't accurate. I just want to play the World Cup to its conclusion first and then, when that's over, there will be a decision.
"That decision will then be announced by me - not by a newspaper.
"While nothing is yet certain, there is nothing to talk about. There's another week to go of the World Cup and then we'll know more. I could also stay at Bayern."
