Xavi Hernandez hailed substitutes Pedri, Lamine Yamal and Joao Felix after seeing his team beat Osasuna 2-0 on Thursday.
Yamal arrived in the first half and took over from the injured Raphinha. He ended up sealing the win late on after great work from Felix.
Pedri also had an impact on his return from injury, and Xavi was happy to see the trio make their mark on the game.
“He [Felix] has been very good, he has come on well, and Lamine and Pedri..., the changes have favored us. We are in another final,” he told reporters.
