Xavi heaped praise on fullback Alejandro Balde, following the game against Unionistas.
Barcelona defeated Unionistas de Salamanca 3-1 in the Spanish Cup Round of 16, and Balde had a good game.
The 20-year-old scored an excellent individual goal, and was a constant threat for Barca.
Xavi has hailed the young player as an unstoppable force, having suffered criticisms in recent times.
“I’m very happy for Balde. I have told him that he has all the qualities to succeed,” Xavi said, as quoted by El Pais.
“He is unstoppable. He has to exploit them, and today he has done it. He has suffered some criticism, but he has to fight back against this situation.”
