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.
Betting on Atletico Madrid's match is very risky right now. Considering their early performance, Atletico Madrid, considered one of the favorites to win La Liga before the start of the year, is now making headlines due to their drop in points. If this trend continues, they could even be out of the Champions League spots by the end of the year. Villarreal is a tough team, and a match against them is risky.
Change your betting strategy, in La Liga you bet more on Real Madrid and Barcelona, I hope this strategy will work for you. Atletico Madrid's performance is not consistent, this team performs well in some matches and loses points in some easy matches. Last season also I considered Atletico Madrid as a tough rival team of Barcelona and Real Madrid, but this season I think Barcelona is a tough rival of Real Madrid and Real Madrid is tough for Barcelona, no team is in a tough rivalry between these two teams. This season only Barcelona can create a possibility of winning the title by keeping Real Madrid in second position, the same thing can happen in the case of Real Madrid.
So I think when Real Madrid and Barcelona play in separate matches, bets can be placed on Barcelona or Real Madrid, depending on the opponent.
