Atletico depreciated in form after the end of last season. I don't know what really happened. It seems that they sold some of their key players. With Atletico current form, I doubt if they will survive in the match. Villarreal is ready to humiliate them if they're given the opportunity. I will be on Villarreal, because they're the favorite.
I am still not quite sure about betting on the Atletico vs Villarreal match. Atletico's performance in the first 3 matches was indeed not good.
In all the matches, Atletico should be favored, but with the poor results beforehand, I think Atletico's chances have indeed declined. However, the situation could become different if Atletico manages to bounce back from that match. Maybe I will skip betting on that match.
