The latest crisis erupted when the referee refused to score a goal from Cristiano Ronaldo in the final moments of the match, which ended in a 2-2 draw.

Ronaldo rose in anger in the face of the assistant referee before leaving the field, throwing the captaincy to protest the failure to count the goal, which the replay footage showed its correctness after the ball crossed the goal line in its entirety.

This case raised questions about why the video assistant refereeing "VAR" was not adopted in these qualifiers, despite the fact that the technology has been adopted for years in European leagues.

The European Football Association "UEFA" decided not to adopt the mouse technique due to the lack of capabilities to apply it in all the stadiums that will host the matches.

And based on the principle of equal opportunities, UEFA preferred not to rely on this technology, rather than its presence in stadiums and its absence in other stadiums.

The qualifiers are witnessing the participation of many small teams that cannot guarantee the presence of mouse technology in their stadiums.

On the other hand, "UEFA" preferred not to adopt the mouse due to the huge logistical preparations that it required to follow a large number of matches held at the same time, which sometimes amounted to 10 matches at the same time.

The Portuguese national team was not the only one to complain about the absence of this technology, as the Spanish national team protested due to controversial arbitration cases during the match that ended in a 1-1 draw against Greece, and the spectators observed clear arbitration errors in the match between France and Ukraine, which ended in a 1-1 draw.
