It's true that it's not only Real Madrid and Barcelona that dominate LA Liga, there are several other teams that do the same. But these other teams are still at a level that can't compete with the two teams. Of course this is the hope of all of us, that we expect some teams to be able to at least keep up with the giants of La Liga.
In last few years we have just two teams domination this Spanish La Liga with some challenge from Atlético Madrid but sadly no other team able to compete with them just because of resources which are used by these two but right now Barcelona is facing some serious trouble in finances but still they are doing amazing job in past we have few teams done good job but sadly most of the time they fail to maintain keep this quality because they have no sources for this and struggle after one or two seasons it's all needed some good and role model financial set up which help these clubs for keeping some good things for maintaining this all quality and good skilled players.
