Adding material to blender sphere

The sphere in unity is too rough, so I imported one from blender with more edges. This sphere does not have any material! It's blank. I want to add the material in unity. However, when I try to add a material to the imported sphere, it looks completely wrong.

But when I apply the material to the unity sphere, everything looks good. Except that it doesn't look like a sphere. So something is wrong with the imported mesh.

I tried to export to .fbx and I also tried to import the .blend - no difference.

On the left you can see the imported sphere. The right one is the normal unity sphere. On the right panel you can see the import options. I tried a lot (without knowing what I'm doing), and it got worse or it didn't change anything.

I know it's hard to give an answer with so little information, but I don't know what to tell you more.
