The 33-year-old Portugal international has an £18.5m-a-year deal which runs until 2021 at the Santiago Bernabeu, but the Turin giants are allegedly ready to offer him a four-year contract worth £26.5million-a-year and, should Ronaldo leave Madrid this summer, a new goal-scoring machine will be brought in.
While a Neymar-to-Madrid move appears to be on the cards, the 13-time Champions League winners could also be tempted to return for Harry Kane's signature if they lose Ronaldo.
The England international has been linked with Real Madrid every other window and, after scoring six goals in three World Cup games to set up a quarter-final clash with Sweden and putting himself in prime position to win the Golden Boot, president Florentino Perez will surely be convinced, more than ever, that Kane is a perfect galactico.
Especially if he ends up leading Three Lions to World Cup glory.
With 135 Tottenham goals to his name in the last four campaigns, the 24-year-old has proved what he is capable of, and Madrid are definitely going to get a prolific goal-scorer like him should Ronaldo leave.
Kane fits the bill to a tee and, if Los Blancos come to the negotiating table with irresistible offers for both club and player, could an exit be in the pipeline for the Tottenham star?
