The U19 team has picked up a crucial win at home to Zaragoza, and that was after conceding the first goal. Paik pulled one back just before half time and Adrià Vilanova and Carles Pérez finished the job in the second half.
With Barça B manager Gerard López watching closely, the Blaugrana dominated from start to finish, with early chances falling to Paik, Lee, Aleñá and Mújica before the Aragonese side had had the chance to do anything of note, but in their first meaningful attack, after 32 minutes, the visitors found the target with a fine long-range strike from Zalaya.
But South Korean Paik soon got the Catalans back on level terms with a fine finish from a tight angle.
Barça were a lot more clinical after the break, and a fine one-two between Aleñá and Vilanova finished with the latter tucking the ball away nicely. From then on, they controlled the game nicely, working down the clock while also keeping things hot in attack.
Pérez then sentenced the tie with a well-delivered shot to leave Barça fourth in the table with 35 points.
