The media in Brazil have reportedly taken issue with Neymar after he was spotted partying after picking up a booking and a one-match suspension against Uruguay while on international duty.
According to AS' David F. Sanchidrian, Brazilian newspaper Globoesporte did not take kindly to the Barcelona star's performance in the 2-2 draw on Saturday and were further incensed when he was seen "out on the town" following the game.
The 24-year-old has now missed five games through suspension for the Selecao since Dunga took over for his second spell in charge.
Indeed, the forward has picked up five yellow cards in the 10 games he's played under Dunga, but he has only found the net four times and was sent off after the final whistle in Brazil's defeat to Colombia in the Copa America last year for his part in a mass brawl.
Selecao Brasileira noted his tendency to lose his cool while playing for Brazil:
The booking—which came after an outstanding showing from Neymar in the first half against Uruguay—will see him miss an important trip to Paraguay on Tuesday, having already picked up a yellow card against Peru.
According to Sanchidrian, Neymar was "involved in an ugly spat with Uruguay defender Jorge Fucile"—one that required his club team-mate Luis Suarez to step in at full-time when Neymar would not shake Fucile's hand.
His form for his country provides a stark contrast with his performances for Barcelona, for whom he has scored 27 goals this season and assisted on 23 occasions.
The forward's discipline has still been something of an issue, though, as he has picked up eight yellow cards for the Blaugrana in all competitions this season—far more than a player who isn't expected to do much defending should earn.
As Brazil's captain and most talented player, the growing frustration with his performances for the national side are understandable.
While disciplinary problems are less of an issue for Barca, as they can still call on the likes of Suarez and Lionel Messi, Neymar is absolutely vital to Brazil both as a goalscorer and a talisman—something the likes of Philippe Coutinho or Hulk cannot adequately replace, as good they are.
The Selecao are not yet at the business end of their road to Russia in 2018, but a win against Paraguay on Tuesday will consolidate their place among the top four South American teams who will automatically qualify, and they'll have to do it without Neymar. If Brazil are to make sure of qualification and put in an improved performance at the next World Cup, he needs to avoid suspension and replicate his club form.
