Do Iranian football use life balls?

be

Some people think that football is a pure game and has nothing to do with politics; Some people regard football as life, which is equal to life and death; Some people regard football as a belief that transcends life and death.

Support glory,

Win the cup of life,

Fight for survival!

Fight for it!

Fight for it! "
