Kylian Mbappe will be announced by Real Madrid this week after leaving Paris Saint-Germain as a free agent.
According to reports, the 25-year-old will get a signing-on bonus of just over £85m (€100m).
Real will pay the signing-on bonus in installments throughout his time at the club.
Mbappe will sign a five-year contract with the LaLiga giants worth (£12.8m) (€15m) a year after tax.
The France captain refused to activate a one-year extension in his PSG contract, just six years after the Ligue 1 side paid £166m for him.
The World Cup winner has taken a pay cut to move to the Santiago Bernabeu. Mbappe was on €75m (£63.9m) gross in the final year of his PSG contract, and was also getting a €30m-a-year (£25.6m) signing-on bonus.
