Chelsea defender David Luiz admits he's nothing like his on-field persona.
Fully charged up on the pitch, Luiz admits that he couldn't be more different after the game is over.
Luiz told the Sunday Mirror: "When I pull on the shirt and play my personality completely changes.
"I am very competitive and very tough. I will fight for the cause and give everything I have. And sometimes I realise that I have to calm down for my own good.
"But away from football I couldn't be more different.
"I'm a very quiet guy and the simple things in life please me.
"I like to stay at home, talk to my family back home and generally take it easy."
