It's part of a cycle, to an extent. Spain has produced a lot of quality players for the past decade or so, starting from their dominant youth sides towards the late 1990s and 2000s that produced a lot of Madrid and Barcelona's mainstays. And to go down a notch, and address La Liga clubs' dominance in the Europa League, a lot of those players have also trickled down through the system, and give La Liga teams a natural advantage. But even aside from their clear superiority in terms of personnel, one has to account for the effort La Liga teams put in European competitions, especially when it comes to the Europa League, in no small part because they have to prioritize Europe to maximize the revenues.
It's kind of mind boggling that Sevilla has won the Europa league for the past couple of seasons, and routinely finish in the La Liga Top 5 or 6, despite a revenue of just €99.93 million a year. Just to put that into context, the last placed Premier League team in 2013/ 2014, Cardiff City had revenues of €114 million, and Sevilla's positional equivalent in the Premier League had revenues of €250 million+. Will those kind of clubs put more emphasis on Europe when compared with the La Liga Top 6?

All this begets the question, what exactly are they doing right, and where is all the Premier League money going? And just by looking at some of the transactions, you get the impression that the football side of things are more well run in certain clubs in the La Liga, when compared to the Premier League in particular. Clubs like Atletico, Club Athletic, Sevilla routinely turn massive profits on players, and reinvest on cheaper equivalents from smaller leagues. eg. Sevilla bought Geoffrey Kondogbia from Lens in 2012/ 2013 for €4 million, and punted him to Monaco in 2013/ 2014 for a profit of €16 million, later replacing him with Grzegorz Krychowiak for €6 million, who is now arguably one of the best defensive midfielders in Europe.
And it's not just one isolated example, they have turned a profit of almost €100 million in the past 5 seasons on a paltry sub €100 million budget, and still managed to win 2 European trophies, to go with the Copa del Rey. Meanwhile the likes of Tottenham wasted almost all of the money they received from the transfer of Bale (which was higher than Sevilla's total budget for the year), and regressed by a couple of notches. And it's not just La Liga teams, Jurgen Klopp built Borussia Dortmund's twice Bundesliga winner, 2013 Champions League final team on a net spend that was almost zero, whereas Liverpool spent €50 million in the 2014/ 2015 season alone, and that after the club record transfer of Suarez.
One has to wonder about the scouting and management structure at some of these clubs, given the relative lack of tangible results when compared with the money invested. A lot of the La Liga are much more intelligent when it comes to that. They sign players on the cheap, develop them, and later sell them for a profit only to acquire more talent and build a conveyor belt of sorts.Part of that is why the likes of Southampton and Swansea finishing in the Top 6 on a consistent basis instead of bloated clubs like Tottenham would be a welcome change. Both clubs are financially responsible, have a good scouting department and develop players from within, routinely replenish players that are lost to bigger clubs, and play good football. Maybe they will take European competitions more seriously, and progress to the latter stages.
