Colombia has been playing the exciting brand of football that Brazilians believe their team should be playing at this World Cup.

They've also been dancing after goals, bringing a spirit of fun to the pitch. Fullback Camilo Zuniga puts it down to coach Jose Pekerman's philosophy of mixing amusement with responsibility.

Zuniga, who will be a key figure in marking Brazil forward Neymar in a quarterfinal Friday, says Pekerman "helped us believe in ourselves ... He drilled into our heads that a Colombian with the ball should have fun, that he shouldn't have to play with pressure."

But Zuniga, who likes to attack down the flanks, says his first responsibility as a defender will be to contain Neymar and help the team keep a clean sheet.
