Bookmakers do not agree with you, see how clubs are ranked to get into the top 4:
Real and Barcelona - 1.01
Girona - 1.06
Atlético - 1.44
Athletic - 2.00
As you can see, only Atletico are in question, and Girona, despite their poor results, is rated well because they have more points.
As I already wrote, Atlético has a difficult situation because they need maximum results both in La Liga and in the Champions League. It is likely that they will fail somewhere (I’m not saying that they are favorites in the Champions League, but beating Dortmund and then PSG/Barcelona is quite possible).
Hmm, Athletic Bilbao's odds to finish in top four seem really tempting. Thank you for sharing it maybe I would give it a try.

Yeah Atletico Madrid are very unbalanced in the La Liga recently while trying to play really big in the Champions League. I think the same about their chances there as well. This would really wear out the players in a quite tight schedule of course. There is even a game in which they will host Girona between the first and second legs of the Dortmund matchup. I really have serious doubts about their dealing with this kind of a fixture in a solid way.
