Barcelona teen Guiu 'won't sleep' after unforgettable debut goal

Teenage debutant Marc Guiu said he will not be able to sleep after snatching champions Barcelona a 1-0 win over Athletic Bilbao just seconds after coming on from the bench on Sunday in La Liga, taking the Catalans up to third.

Xavi Hernandez's Barca will face leaders Real Madrid next Saturday in the Clasico just one point behind their bitter rivals, and second-placed Girona, who beat Almeria 5-2 earlier on.

For a long time it seemed like Barcelona would not find the breakthrough against their Basque visitors but striker Guiu, 17, netted under a minute after being thrown on by Xavi.

The forward was slipped in by the silky Joao Felix and slotted past Unai Simon, who got a hand to his shot but could not keep it out.

"Tonight I won't sleep," Guiu told DAZN.

"I can't believe it, I can barely breathe, I'm enjoying the moment."

Guiu became the latest on a conveyor belt of youths to make their debuts for Barca as their La Masia academy continues to produce gems.

"It surprises me that they aren't scared, I see them with a spark, they look at me with a face saying 'Put me on, you'll see that it will go well'," said Xavi.

"I saw that with Gavi, Balde, Lamine, Fermin, and with Marc, he doesn't look afraid."

Xavi brought on Guiu in the 79th minute and with his very first touch he broke into the area and then with another confidently scored the winning goal.

"It's the best day of his life, surely," added Xavi.
