Brazil head coach Tite blasted the video assistant referee (VAR) and labelled it "inconceivable" that Nicolas Otamendi was not sent off for an elbow in Tuesday's 0-0 2022 World Cup qualifier draw with Argentina.

Raphinha was floored and left bloodied after the 34th-minute incident where Otamendi flailed his arm into the Brazilian midfielder's face.

Otamendi lifted Raphinha to his feet with no sanction from referee Andres Cunha, nor any VAR intervention in the aftermath leaving Tite flabbergasted.

"It's impossible not to see the elbow. Was it decisive in the result? I do not know," Tite said during the post-game news conference.

"Was it a great match for both teams? It was. Great game between them. Tradition, technical quality. Now, there's a component that has to be equal, for those who have the discernment to see.

"But a high-level VAR referee cannot work like this. It is inconceivable, and that is not the term I want to use, but I use it because I am educated."

The result in San Juan leaves already-qualified Brazil six points clear of second-placed Argentina in the CONMEBOL World Cup qualifying standings.

Argentina officially earned their spot in Qatar one hour after full-time when Chile were beaten 2-0 at home by Ecuador.

Brazil return to action away to Ecuador in late January when CONMEBOL World Cup qualifying resumes.
