Turin: Juventus striker Gonzalo Higuain has warned his teammates that Barcelona will not have another off day like the one that put them on the brink of elimination to Paris Saint-Germain in the Round-of-16. Barcelona were beaten 4-0 in the Parc des Princes and needed a miraculous comeback in the return leg to book their place in the quarter-finals, with Sergi Roberto eventually rounding off a stunning 6-1 win into stoppage time.
