Thank you very much gatohdo for your help! Now it works!!! Without your help would never came to this point! Hope this is also helpful for others. Now the only problem is the missing texture around the pitch: The only missing texture is the texture surrounding the pitch. If I import an origninal EA stadium in blender the texture around the pitch is missing. Then I assigned a texture and in blender I can see the texture, but then in the game all texture are ok, and the only missing texture is the texture surrounding the pitch. What I have to do to solve this!
