Barcelona defender Gerard Pique is in awe of their attack.
Their all-star forward line of Lionel Messi, Neymar and Luis Suarez have played a huge part in that success, and Pique admits he cannot recall an attack like it.
"I've never seen a trident like this.
"We've enjoyed great players, but the quality they have, how they complement each other, the connection they have between them....we're talking about something unique," he said.
