Spain's U21 side called up Ansu Fati as a replacement for Barcelona teammate Carles Perez.

"Carles Perez has left the Under-21 national team camp due to muscular problems, which would have prevented him from being available for the Montenegro vs Spain match in Euro 2021 qualifying," released the Spanish Football Federation in a statement.

The 16-year-old Fati could make his Spain debut against Montenegro this Tuesday.
