Speaking ahead of his country's World Cup quarter-final against France, the Germany international insisted that he has not made any decisions about his future.
"I've said all along I will not make a decision on my future during the World Cup," he told reporters.
"As soon as the tournament is over, I will make a decision and something will be announced. But it will not happen while I'm here and I haven't signed anything."
Kroos has just one year remaining on his current contract with Bayern.
