Ousmane Dembele was back showing his positive side against Tottenham Hotspur after a difficult week.
The 21-year-old had made the news at the weekend after showing up two hours late for training, by which point the rest of the team had all but finished.
That led to talk, yet again, over Dembele's long-term future at Camp Nou - could Barca really depend on a player who can't even show up for training properly?
Whether they can or not pretty much purely comes down to how good he is and whether it's worth it to keep patient and hope he learns.
And it only took seven minutes of the game against Spurs for Dembele to remind everyone why they probably should take that chance on him.
The Frenchman won the ball on the halfway line before sprinting past two defenders and slotting the ball home to score a wonderful opener.
It means that Dembele has now scored nine goals and assisted another four despite being in and out of the side.
That record is enough that Ernesto Valverde was asked after the eventual 1-1 draw with Spurs whether the issue with Dembele was now resolved - and the Barca boss had a wonderful answer.
"I don't don't know," he said. "You [press] can write what you want - we still have training tomorrow [laughs]".
That just about sums the situation up.
Valverde did also take time to commend Dembele for his goal, although he also stressed that it was a team performance and not all about the winger.
"Dembele scored a goal in which he made the most of the space and was cold-blooded in finishing it," he told reporters."But we are a team and we all pull for the same goal for the team."
It certainly seems as though Dembele has a little further to go before Barcelona are completely happy with him, but if he keeps scoring goals like the one on Tuesday night, that time will come sooner rather than later.
