Tricky one, solution will be very interesting: Grünwalder Stadion, currently home to 1860 Munich, FC Bayern II and Türkgücü, will have to undergo some (major?) reconstruction. Turkgücü are top of the League of the Regionalliga Bayern, so might as well get promoted to the 3. Liga in summer. No chance for the three clubs playing in the same league to share one ground only. 1860 Munich's requests to share grounds during reconstruction with either Unterhaching, Regensburg, Ingolstadt or Augsburg were all turned down by these clubs. Turkgücü actually planned to play their matches a couple of hundreds of miles away from Munich in the Rhine/Ruhr area (large turkish community there), which was turned down as well.
