Raphinha hit the winner as Barca won 4-5 in injury-time.
The match ended in a brawl sparked by the Brazil international and he later said: “I'm someone who respects everyone.
“When I was leaving the pitch, people were insulting me. I returned the insults. I know I shouldn't, but it got heated with the Benfica players... they preferred to insult me. "I’m someone who doesn’t let things slide. If they respect me, I respect them. But if they insult me, I won’t stay silent. It's normal after a game with such an ending.”
He also said: "We knew it was going to be a difficult game. I know how difficult it is to play here against Benfica. They have very high-level players. We didn't get carried away with being 3-1 down. It was a spectacular game for the spectators. Anyone could have won."
Asked if it was a career best moment, Raphinha concluded: "Yeah, maybe."
