Just gonna ballpark now.
Signed for 75m in 2019 on a contract running until 2024. That's 15m per year amortisation.
In 2020, signed a new deal until 2026. 60m remaining, 10m per year (still under the old rules).
10m of his fee remains. If he extends this summer (reportedly 3 year contract), that's gonna be 3,3m per year. We'd save 6,6m on amortisation.
Re his salary, he's set to receive 22m gross next season according to the leak. His contract average was 19m. Let's suppose he takes a significant cut, 15m gross for the next three years. 7m remain to be paid. If evenly distributed, that's 2,3m per year.
In total, his renewal would save us about 11m on the books under the assumptions above.
Significant, but less than half of what's needed for Nico.
Financial year ends today, we'll be much smarter in the coming days.
