Depends on the rival… There’s about 4 PL clubs I would always root against, the rest I’d probably support or be neutral at least.

Nah mate, you can basically pick up the ball with 2 hands and walk across the field. Kind of like rugby. As long as you are not the one scoring the goal it’s allowed.

In defense however, you are not allowed to have arms. Unless you’re wearing a very specific shirt.
