Brandao patiently waited for the arrival of Thiago Motta in the tunnel and headbutted him for reasons not yet known.
At the end of PSG's 2-0 Ligue 1 home win, television cameras showed players and security personnel milling around the tunnel as blood poured from midfielder Motta's nose.
President of Paris St Germain Nassar al-Khelaifi, told a Canal Plus TV reporter that his club would be registering a complaint against Brandao and that he (Brandao) should be "suspended for life....he is not a football player".
Al-Khelaifi added that the Brazilian "waited for Thiago Motta in the tunnel and attacked him with a headbutt".
The incident overshadowed PSG's win.

This is very wrong,I hope they take the right actions against him,if you do some-things on the field of play,we will understand that emotions in @ high,but waiting to assault someone in the tunnel is in the extreme.
