However, the risky Paulo Dybala, who scored twice as the Italian champions dumped Barca out at the quarter-final stage last season, is fit to partner Gonzalo Higuain in attack. "If you leave Messi with open field you know what's going to happen".
However, Juventus standout Paulo Dybala was completely outplayed by Messi, his Argentina teammate; centre forward Gonzalo Higuain was almost invisible - just like last season's final - and the Turin squad hardly put up a fight in the second half.
The 23-year-old remained at Italian champions Juve, though he refused to rule out a future switch to Barca to play alongside countryman Lionel Messi.
"He started well but he's got to stay calmer". Messi fired a shot from just inside the area, with the low, perfectly placed shot nestling in the far corner of the net, leaving Buffon helpless.
"We've already said Messi's renewal is signed and that he'll be at Barca for as long as he wants, the same with Iniesta". But in general we've got to be more applied.

Aside from the goals and victory recorded by Barcelona over the weekend, there was more to celebrate about for Lionel Messi.
This is likely Buffon's final season, and the 39-year-old goalkeeper is not having an easy time of it. Juan Cuadrado is suspended while Giorgio Chiellini is expected to miss out with a calf injury. Dani Alves has departed as well, with Mattia De Sciglio taking his place.
