Former Bayern Munich defender Javi Martinez can see Hansi Flick taking charge of Barcelona.
The former Bayern coach is a candidate to succeed Xavi at Barca this summer.
And ex-Spain international Martinez says: "Flick's way of playing is total Bara. He is a very clear coach, he always tells you what he thinks to your face. He is calm. You have to mess with him a lot to get him angry.
"In the locker room he first calms everyone down and then speaks. Flick's training sessions are intense, but they are always with the ball. In Germany we all trained in the afternoon with a physical trainer and that's where all the players changed. It's a different culture.
"Flick's way of playing is total Bara. We played with him in the Pep style, with the centre backs and the ball coming out from there."
