The Brazil international blasted the use of VAR to award Manchester United a late penalty in their 3-1 Champions League round-of-16 second-leg win at Parc des Princes last week that secured a 3-3 away goals success.
Injured Neymar could only watch on from the stands and later the touchline as his teammates threw away a two-goal, first-leg lead following two Romelu Lukaku goals and a Marcus Rashford spot kick, awarded for a Presnel Kimpembe handball after a VAR review.
"This is a disgrace," the 27-year-old raged on Instagram at the time. "Four guys who know nothing about football watch a slow-motion replay in front of the television.
"It was nothing! What can [Kimpembe] do with his hand while his back is turned? Go f--- yourselves!"
Neymar watched last Wednesday's match from the stands, having returned from Brazil where he had been recovering from a second fractured fifth metatarsal in his right foot.
But sources have told ESPN FC that Neymar is ahead of schedule in his recovery from his latest injury and even wore boots during his recent stint in Qatar.
