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 players 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 its team or we could eventually have another team win La Liga trophy base on how Madrid has been able to make its squad get stronger in the last couple of seasons, and this isn’t a different case this season.
It's true that they never miss the UCL, in fact every year they always bring in top players, their finances are stable which makes Madrid always the strongest candidate to win the UCL every season, this is what all clubs should set an example to be able to maintain the club's finances so that they can Competing with big clubs, Barcelona should have to follow the example of its rivals in financial matters so that it is stable under any circumstances, it is difficult for Barcelona if financial matters always concern them because the problem lies there, so whatever happens Barcelona still has to compete even with current players. At least Barcelona is always consistent in any league so that they always get a pot of money from sponsorships or player sales.
