A spectacular bicycle kick by Antonio Sanabria and a second-half header from Omar Alderete secured Paraguay a well-deserved 2-1 victory over Lionel Messi's Argentina in Thursday's South American World Cup qualifiers.
Argentina struck first in the 11th minute when Lautaro Martinez smashed in Enzo Fernandez's deep pass.
Initially flagged for offside, the goal was awarded after a VAR review.
Paraguay almost equalized moments later, but Gustavo Gomez's header rattled the crossbar.
