I think you're honestly wrong, in my opinion Real Madrid gives more importance to the Champions League, in fact the season in which Barcelona won (two years ago) they actually abandoned La Liga to focus on the Champions League. I don't know about Manchester City, but for Real Madrid the priority is the Champions League.
Sometimes it’s difficult to predict what will happen but i don’t think Barca will have a chance in winning the La Liga this season with the differences in quality between their signings and that of Madrid but we never can tell.
Anything pertaining La Liga right now will most likely be Championed by the current formidable Madrid team, The present Barcelona team no longer has the kind of player that matches the level of current Real Madrid team, And I believe that Madrid will be dominating for a least another couple of seasons and until Barcelona is able to fix up their team or we could have any other team to win la Liga trophy base on how Madrid has been able make its squad get stronger this couple of years, and this is isn’t a different case this season.
