The return of teenage sensation Lamine Yamal to Barcelona's starting lineup following an injury layoff is what inspired the team to a 5-1 thrashing of Mallorca, manager Hansi Flick said on Tuesday.

In the second round of the Copa del Rey, fourth-division club Barbastro ousted top-flight club Espanyol 2-0, while Celta Vigo trounced Salamanca 7-0, Las Palmas defeated Europa 2-1 and Valladolid beat Ávila 4-2.

Barcelona cruised to a thrilling 5-1 win over Mallorca on Tuesday evening to silence their doubters and strengthen their position at the top of the La Liga standings. A full return of wonderkid Lamine Yamal and a growing confidence amongst the Catalans proved to be a recipe for success for Hansi Flick - who recorded his first league win since the start of November.
