Juventus defender Giorgio Chiellini has warned that Barcelona are still a threat in the Champions League quarter-finals, despite the 3-0 first-leg result.
The Bianconeri eased past the Catalans in the first leg, which gives them a big advantage heading into the second leg in Spain on Wednesday.
However, Barca overcame a 4-0 deficit against PSG in the last-16, and Chiellini remains wary of their ability to fight back.
"We've only got half the job done," Chiellini told Sky Sport Italy. "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 manager Luis Enrique claimed that it may be easier to overcome a 3-0 deficit against Juve than the 4-0 deficit against PSG, but Chiellini is determined to disappoint him.
"He's right — mathematically speaking," Chiellini added. "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."
