Giorgio Chiellini has told Italy's Sky Sport that Barcelona are like "sharks who scent blood" as he warns that Juventus' Champions League quarterfinal tie is far from over.
Juve head to Spain on Wednesday with a 3-0 advantage from the first leg, but Barca's record-breaking recovery from a 4-0 first-leg defeat to Paris Saint-Germain in the round-of-16 is enough of a warning that the tie still has some way to go.
Chiellini, who was part of the Juve team beaten 3-1 by Barca in the 2015 final, is therefore not jumping to any conclusions.
"We've only got half the job done," Chiellini said. "We've got to try to disrupt Barcelona's game and score because that would be a decisive injection of belief and a lot depends on our attitude.
"We need to be compact and show no fear. They are like sharks who scent blood and finish you off. We've got to keep them as far away from our goal as possible."
Barca are underdogs despite their 6-1 win over PSG in the last round because of Juve's defensive strenth and overall experience, but Barca coach Luis Enrique is of a different view and claims it may actually be easier to recover a three-goal deficit against Juve than it was to bounce back from four down to PSG.
"He's right -- mathematically speaking," Chiellini said. "Everybody tries to see things their own way and he's trying to prepare a comeback which would be historic, but we're going to try and spoil his last Champions League game on the Barca bench."
Juve took a bold approach to the first leg with coach Massimiliano Allegri naming Mario Mandzukic, Paulo Dybala, Juan Cuadrado and Gonzalo Higuain in an attack-minded starting XI.
Many saw that as the key to their win with Barca not expecting to be attacked so ruthlessly and Allegri is hoping to be able to name the same team at the Camp Nou, although there are doubts over Dybala, who scored a brace in the first leg.
Dybala limped out of Juve's 2-0 win over Pescara on Saturday after being injured by former Inter Milan midfielder Sulley Muntari.
Allegri said he is hopeful that the Argentine will be fit, however, and although he did not train on Sunday -- instead receiving physiotherapy -- it is reported that Dybala's ankle injury is not so serious and that he will be able to train again on Tuesday.
