This isn't just a tussle. Corluka was practically in a goal scoring position and Busquets takes him down with a goddamn judo-throw over. It would be different if it was shoulder to shoulder and he out muscled him, but that is far from the case.
Yes, Rakitic should have nailed that header, but the fact remains shit like that shouldn't happen.
