Sanguine Football is a contact sport. Whenever players challenge for the ball they use their arms. Oscar could have run straight through it, he chose not to. Pathetic.
It is a contact sport, but (exaggeration here) you can't rugby tackle someone. He deliberately put his arms out to impeded Oscar. The fall might have been theatrical but there was contact.
So next time Countinho is clothes lined in the area by an arm it will be no penalty? Because arms are now allowed to be used to tackle according to you.
