Overview

• Asked about Argentina’s call-up plans, Alonso said Friday, “If it depends on us, he stays with us,” indicating Madrid intends to refuse the under‑20 release.
• The Argentine FA plans to send representatives to Europe to seek agreements with Madrid and other clubs over player availability, according to reports.
• The U-20 World Cup runs Sept. 27–Oct. 19 in Chile and partly overlaps the October international break, yet participation could still cost Madrid up to seven games including prep and travel.
• Mastantuono has featured in every Real Madrid match this season under Alonso, reflecting his growing role in the first-team setup.
• The 18-year-old recently made strides with Argentina, wearing the No. 10 in Messi’s absence and later apologising for a reported on-field incident after choosing to shoot instead of pass.
