Because Gladbachs sporting director said that they dont let him go and have planned with him.
So i guess we will see Sven Ulreich in the future there and that Munich try to get young player .

I also read in several sports media which reported that, Borrusia Mochengladbach confirmed that they would not let Yann Sommer go to Bayern Munich However, there is one media that reports the opposite.
I will quote a bit from the news, yesterday we got the news that Gladbach will not let Yann Sommer join Bayern Munich this winter. it should be over, but now there's a new twist. according to the very reliable Florian Plettenberg, the goalkeeper himself is working hard to get his transfer completed quickly this season.
IMO, actually Bayern could give Bayern Munich's second goalkeeper Sven Ulreich a chance. Bayern doesn't need to work hard just to find an ideal replacement, after all there are many choices other than Yann Sommers who is still young like the Croatian goalkeeper who performed quite brilliantly at the Qatar world cup yesterday. but I don't understand, what exactly are the criteria as a candidate to replace Neuer.
