Crafting the transfer analysis

I’m planning a quick translation of the context around players and clubs. I need to check the plausibility of the 12m/year wage, which might include gross salary and bonuses. I’ll consider Fenerbahçe's wage structure and typical January signings, which last around 3.5 years.

Should I verify this with sources or gather the original report? It would help to know if the wage is net/gross or if bonuses are included, and I'm curious if the user has any links. Let’s finalize how to present this!
