A sport which requires a BRAIN and FITNESS unlike american football where you run for 5 seconds and stop, if you think soccer is easy, think again, watch the top 3 leagues on the world English Premiership, Italian Serie A, Spanish La Liga and you will see how they play, soccer you CAN make contact unlike basketball where you put one hand on the guy and its a foul. With soccer it can take more than 5 years to be a good player with all the skills involved in the sport, soccer players need to be running for 90 mins OFFICIALLY not 85 minutes 90 because of stoppage time unlike american football where you run for 10 mins. You need to have a passion for soccer to play it, its useless playing with no passion because you wont get anywhere, soccer has the most passionate fans out of any sport and if you dont believe me, search soccer ultras on the internet and you will see, the point is that soccer is the best sport and requires the most out of any other sport.
