Real Madrid is the favorite to win in La Liga and the Champions League so it's not strange if people think Real Madrid is focused on the UCL. As far as I know there is no team that is thinking about focusing on the UCL and ignoring the competition in the League. Usually every top team will target to win the League and UCL. Real Madrid are the kings of the UCL but it seems unlikely that they will ignore the domestic competition. Real Madrid can get both and almost every season can get one of them. They have a solid squad. I think even this season they have a better squad than the previous season.
This your conclusion about Real Madrid’s squad depth to be better than that of the previous season can be as a result of Mbappe that joined them for next season. They are showing a great squad to us all there and I don’t expect nothing but the less. Even so, other teams can also prove themself worthy of their squad when they meet each other head to head. Every team always fights for the best and fighting for two trophies or more should be the aim of every club, so they should not be left out in the trophy race if they lose one of them along the season. Real Madrid is a team that has never won treble before so wining more than two trophies or fighting for two or more trophies at a time won’t be a big deal for them.
