Reporter: There will be no problem with Mastantono playing for Real Madrid in the Champions League

In the first round of La Liga, Real Madrid defeated Osasuna 1-0 at home, and Real Madrid's new player Mastantono completed his La Liga debut. Previously, some media questioned Real Madrid's registration of Mastantono with the B team, believing that they were taking advantage of loopholes in the rules.

In response to this, reporter José Félix Díaz said: "Don't be deceived by them. There will be no problem with Mastantono playing in the Champions League for Real Madrid."

Mastantono is 18 years old and an Argentine striker. He joined Real Madrid from River Plate this summer for a transfer fee of 45 million euros.
