Barcelona are no longer considered top competitor for the UCL because they've failed entirely to bounce back to their feet in major tournaments. They can't prove themselves worthy enough to face the top elite clubs. While Real Madrid have focus and priorities to meet every season. Los Blancos have everything to worry about and winning becomes very compulsory for them. Carlo Ancelotti is here to make sure they achieve the ultimate goals which is been set out for them. The UEFA Champions League have been their main priority every single time.
Barcelona is still very much Worthy to face top elite teams and still pose a threat to them, I know you would want to make reference to all that they have got as a challenge to tackle in recent times but then look at their performance so far, they have been struggling but still managed to get decent finish and positions so they aren't so terrible that we wouldn't be able to have something to really write home about them but then let's take another look at the fact that if they face top elite teams, they are going to win if given the chances so taking them for granted may literally just be the worst thing we may be doing at rhia time.
