That Barcelona team really needs some serious hardwork and for now they are no way going to be in the standards of real Madrid because Real Madrid gotten everything covered from talents to skills and all are of the right age @ young and vibrant. Barcelona needs serious back up and players in that squad before they can seem to get things working because if they start the new season like this they are no way going to make it to the battle the league with Real Madrid.
My view of Barcelona is also the same because when compared to what Real Madrid has achieved, of course it is still very doubtful that Barcelona will be able to match its performance with Real Madrid next season. Because Barcelona, apart from still needing talented young players, also still needs experienced players in their own squad so that the talents of the existing young players can be more easily channeled on the field or in important matches in the League.
Barcelona cannot challenge or rival Real Madrid for the La Liga title next season because they don't have a good squad that can perform better than Real Madrid's squad. Barcelona is still in the rebuilding stage, so I don't expect them to win the La Liga title next season. Barcelona's target next season should be to finish in the top four of the La Liga table so that they can qualify for the UEFA Champions League competition. If Barcelona's new coach can build up Barcelona's squad in this transfer window and the next transfer window, maybe they will start challenging Real Madrid for the La Liga title.
I don't think Barcelona have the strength of moving around in transfer window because of their financial situation now, even before the starting of the season it should be better Barcelona to agree to just stay behind real Madrid because they can stand it, second place is for them the earlier the believe it better for them, Real Madrid are currently the most strongest teams all over the world not Laliga alone, and they are fit to play and win any of the competition without any fear. Among all the leagues, I think only home league required a consistent performance to be able to maintain it, and already they are built in that.
