I may be wrong, but because the Saudis are making very high offers, the player market has started to increase the prices of players when they realize that a Saudi club is interested in that player. For example, if a team has player X who costs 30 million dollars, all it takes is for a Saudi team to make an offer of 60 million dollars for the team that has player X to increase the price to 70 million, so any team in Europe that wants player X will have to negotiate that high amount. This is putting players who are not even worth a high price as if they deserve that high value.
