Ousmane Dembele was delighted to make a winning debut for Barcelona in victory over Espanyol.
The Frenchman saw action in the second-half of the 5-0 rout.
He later told BeInSport: "I am very happy, it is a unique opportunity to be next to the best player in the world (Lionel Messi).
"It was a great victory, I felt a lot of emotion. It's a dream come true for me.
"(Coach Ernesto) Valverde told me that I should remain calm. I hope to continue like that."
