I am Baslo Stephen a 31 years old soccer player. I have 24 years of experience playing football/soccer. The things that i have noticed in whole my life are that soccer balls depend on the type of construction, condition, and materials. Well, i couldn't explain it here but the PLUS MATHS have explained everything very well. Furthermore, you may google your questions to get the exact answers.
Knowing about the fact you are seeking for is important to know about coz it can improve your game.
