The Spaniards play a little more accurately, and therefore became leaders of group B.
In the first round of Group B Spain and Portugal played a draw - 3: 3. In the second round, Spain beat Iran 1: 0, and Portugal with the same score took over Morocco.
Thus, both teams have identical goals scored and conceded goals, as well as equality in a personal meeting.
Now Spain leads Quartet B, because it earned less yellow than Portugal - 1 against 2, notes Phil Keatromilides, presenter of The Spanish Football Podcast.
If the points are equal in the World Cup, the goal difference is taken into account, then personal meetings, scored goals and yellow cards.
