This is the new trend in the football transfer market right now, the influx of the Saudi's investment in football is already causing distortion in the transfer market at some point because this makes these clubs think their player in quote worth more, and they may be selling their player below his actual market value which makes them to reevaluate the player's valuation, whereas the Saudis put up these prices on these players because the wants to try to entice them to come without considering their real market value.
Teams from the SPL know that if they don't make a very high offer on a player and only make an offer based on the usual market price then it is very likely that the player they want will not be interested in accepting their offer. Because they realize that the SPL is not as big as other leagues in Europe. So European star players will definitely think several times about accepting an offer from an SPL club. But by offering very high prices or very high salaries, European star players will be quite interested in the salaries offered. And in this way the SPL clubs managed to bring in several European star players. In fact, not only old star players but also several young European star players, we can now see many joining clubs in the SPL. And yes this is one way of their investment in attracting the world's attention to them.
