No. If teams werent able to play dirty, football would be boring because the better team would win pretty much every time. I say this as a barca fan, so my team has dropped points a lot this season from dirty playing, and it definitely doesnt look pretty, but it's necessary for worse teams to compete. Also, a lot of yellows are accidental.

Im a barca fan, and even i will agree bellingham played great. He pulled a goal out of his ass like messi in the 2022 world cup, then nutmegged mats (one of the best keepers in the world). Im not even scared of mbappe anymore, its this guy.
