What happened: Spanish outlet Diario AS reports that a knee knock Nico Paz has been carrying is not improving. With the World Cup just days away, the midfielder is now at risk of being ruled out of the tournament. No formal decision on his availability has been announced.

Why it matters: Paz has become one of Argentina's brightest emerging talents, and a late withdrawal would force a reshuffle of the squad's attacking depth heading into the tournament. The same Nico Paz whose future Como has fought to protect now faces a fitness race that could overshadow his summer.

What to watch: Watch for an official fitness update from the Argentina camp and a final call on whether Paz makes the World Cup roster in the coming days.
