Dunga disapproves strongly of Neymar’s hairstyle – hair should be properly combed and NO COLOUR .
He disagree with Neymar’s Caps -Caps should have the country’s flag on them -NOT ANYTHING ELSE EVER
He objects strongly that Neymar’s fans and the rest of the team should have given so many Neymar tributes after his back injury.
He also probably objects to Neymar being so inconsiderate as to get himself injured just when his team needed him so much – but he hasn’t said that yet.
Get a life Dunga.
All the things that Dunga considers wrong about Neymar and the Brazilian team here..

There is also a report that Neymar does not actually use his brain much while playing football.
Now that sounds like something Dunga might have said but actually it has nothing to do him.
A scientific study done on Neymar – involving MRI brain scans etc has revealed that Neymar’s brain activity while playing is very less and that he is playing instinctively most of the time.It’s as if his wizardry comes from his brain being on auto pilot while playing.
“Reduced brain activity means less burden which allows (the player) to perform many complex movements at once. We believe this gives him the ability to execute his various shimmies,” said Eiichi Naito, a researcher with Japan’s National Institute of Information and Communications Technology.
