I can't imagine how lonely the El Clasico would be without Messi and Ronaldo. Totally unforeseen circumstance occurred in Laliga and Barcelona before the new season started.
Looks like there must be a new star to fill both clubs. We worry too much about losing Ronaldo and Messi, and maybe it will happen soon. In 2-3 years they may not play again due to declining physical factors. For now maybe La Liga will not be as attractive as it used to be. But I think Barca and Madrid will get new stars, but I don't know when.
If I admit when Ronaldo left I had lost a bit of interest in seeing La Liga, then Messi left, that made me even more disappointed.
La Liga is definitely loosing a little bit of its glamour without Ronaldo and Messi. Barca is in big financial problems and they will have to turn to their youth players a bit more rather then buy everything on the market for the next couple of years. I actually think this is the best thing that could have happened to Barca. They were always the good when they had a couple of their own, home grown, players in the team.
