According to TyC, the Argentine national team is currently facing a worrying problem ahead of the World Cup: they lack sufficient matches to prepare.
First, there's the Finalissima against Spain. Due to the instability in the Middle East caused by the situation in Iran, this match will not be held in Qatar as originally planned. However, due to the tight schedule, the match is still scheduled for March 27th, with the specific venue yet to be determined. Meanwhile, Argentina's friendly match against Qatar, originally scheduled for March 31st, is practically impossible to take place given the current situation.
Too badly, the preparatory matches against Mexico and Honduras, originally scheduled for June 1st-10th in Las Vegas and Miami respectively, have also been cancelled by the Argentine national team. Unless the Argentine Football Association can find opponents at the last minute, Scaloni will have to use the Finalissima as a testing ground to refine his ideal lineup and formation.
