Answer

Hey Farhana!

Your sentence is perfect! You used a negative inversion. ( Never have I ever seen part) It needs no correction. It is used to add more emphasis.

Hi Farhana! 
You can say the first part of the sentence like this: 
I have never seen people clash over a football match where their team/ country is not playing. 
The rest is natural.
