Most expensive players for Real Madrid

As we can see, from the most expensive players, in Real Madrid history, Bale, Ronaldo and Tchouaméni, are above the 7 on average rating, at the time they were playing in LaLiga. We should not take the frenchman in account, he has only play one season in Spain. On the other side, Eden Hazard, the most expensive player for Real Madrid (115 Millions), does not reach that number 7. Will Jude Bellingham become a world class player, here in Spain, or will he fail as the Belgium star?
