Thank you for this good debate argument.

I think that Real Madrid is the best because Manchester united doesn't have good defense and Real Madrid has a really good attack.

Also in many electronic games, most people choose Real Madrid because they have a really good stamina. Also they attack and defense well so they don't loose many times like the Manchester United.

Many people like badminton more Also many old people can play it because the rackets are light and you can play badminton anywhere because, you can play in a park but, for tennis you just can play it at a tennis court. There aren't much tennis courts around much places so badminton is a better racket sport.
