Barcelona coach Xavi was delighted with Raphinha and Pau Cubarsi after victory at PSG.
Raphinha scored twice as Barca won the first-leg of their Champions League quarterfinal 2-3.
Xavi said: “Everyone has taken a step forward. I would highlight the group. I have told them that we have to be supportive. And the team has done an immense collective job.
“In the Champions League, maybe yes (it was the best win). But not from my time as a coach here. We have an advantage of only one goal. We have to continue. But yes, very happy because this victory represents a change in the competition.
“He (Cubarsi) is at an extraordinary level. I'm running out of praise. He wins duels, he has personality, he competes like an older player.
“I feel proud to play with teenagers.
“For me Rafa is a differential player in his potential. One of the best in the world in space, he has goals, finishes plays, presses high, is the first, and always works for the team. He is always looking to improve. Very happy for Raphinha, he deserves it."
