Part of it, I believe, is other leagues have started to replicate how La Liga would bank on its marketable names that featured in the league; PSG have made a habit of signing big names as a means to milk the money a player like Lee Kang-in. It's also a side effect of La Liga clubs overspending and now having to cut back as a means of continuing to operate.

It's also not very exciting as it once was. Spanish football is more technical and can be boring because teams just try to out-muscle each other in this department. The amount of hoofball games I have seen over the years where it's the smaller teams that tend to use traditional wingers to break through defenses with pace.
