Ernesto Valverde gave a first-team debut to Ansu Fati at the age of just 16, taking to the Camp Nou pitch against Real Betis for just over 10 minutes.
The forward, from Guinea-Bissau, has been training with the first team this week due to injuries to key attacking players, such as Lionel Messi, Luis Suarez and Ousmane Dembele.
Carles Perez also played in the win against Betis, another La Masia product. Fati, meanwhile, will play under the orders of Victor Valdes with the Juvenil A side this season and will play in the UEFA Youth League.
Now, the Camp Nou crowd know all about him as he daringly took players on, becoming the youngest player to play for the club since Vicente Martinez in 1941.
At the end of the match, Fati had a nice surprise waiting for him in the form of Messi. The Barcelona captain waited for him at the end of the tunnel and gave him a hug.
