I doubt that a soccer player could outskill a basketball player on a basketball court any day, but the same can be said when the roles are reversed.
On top of all that running, you need to have excellent ball control, precise passing, and near acrobatic shooting. Even with hockey, or basketball, you get tv timeouts, however many else a coach can call, and regular stops of the clock. In soccer, no such luxuries exist. It's grueling, it's energy consuming, and that's why it takes greater skill overall.
