Brentford have extended Chris Long's loan spell from Everton until the end of the season.
The 24-year-old's current contract with the German and European champions runs out in June 2015 and there have been suggestions that he could be convinced to move to Manchester United in the summer.
Kroos and Bayern have been in negotiations over a fresh deal for a while, but the Bavarian giants are reportedly refusing to meet his wage demands.
However, the midfielder insists that he is no hurry to sign on the dotted line and dismisses suggestions that there is deadline to the discussions.
"We have focused on signing a new deal for some time," the Germany international told Kicker-Sportmagazin. "However, we did not reach an agreement in January.
"I want to fully focus on the 2014 World Cup. I do not want to discuss contracts during the tournament.
"There is not a deadline for my future to be sorted."
