Paris Saint-Germain defender David Luiz has slammed Brandao for his 'unacceptable' headbutt on Thiago Motta.

PSG's 2-0 win over Bastia on Saturday was marred by allegations that Brandao headbutted Motta in the tunnel at Parc de Princes, leaving him with a bloody nose.

Les Parisiens' president Nasser Al-Khelaifi has called on the Brazilian to be issued with a lifetime ban, while Luiz was also quick to condemn his compatriot.

"We have a great job in the world to show a good example inside and outside the pitch. I think many kids in the world want to be us so they know about everything," he told reporters.

"That is not part of football. I don't agree with this. Sometimes on the pitch you are more vulnerable with something and they speak bad things, but that's normal in football.

"But when you wait for someone outside the pitch to do a bad thing. I think that's not [acceptable]. That's not part of football."

Goals in either half from Lucas Moura and Edinson Cavani sealed the victory for the defending Ligue 1 champions.
