Barcelona coach Ronald Koeman says they must learn from their 3-0 home defeat to Champions League opponents Juventus.
Cristiano Ronaldo struck two penalties, along with Weston McKennie hitting a volley.
The Azulgrana team finishes as second in the group with five wins and one defeat.
Koeman insisted, "I think that you must give us a chance to learn.
"We have played two matches against them, in the first we were much better, today the first half hour, you have to see the team, the idea of the players, it is a lesson that we have to learn.
"They have come out much more involved."
