Belgium and Italy are the only two nations aspiring to finish the campaign winning all their matches. Both nations have already qualified for the final tournament, but they can still complete the challenge of not losing.
If they do it, Belgium and Italy will finish the qualifying campaign with 30 points out a possible 30. This is, without doubt, an attraction for them both.
This was also Spain's target. Robert Moreno already said it in several press conferences. He wanted to see Spain win all their matches.
But Spain drew 1-1 against Norway, dropping 2 points. As such, only Belgium and Italy can finish the qualifying campaign winning all their matches.
Kazakhstan, Russia and Cyprus are the teams that Belgium face as they try to reach this target. Italy must beat Liechtenstein, Bosnia and Armenia to achieve this.
