I think that the problem is exactly that, they are making things really difficult because Diego Siemeone hasn't made the changes they needed to make to the team, and this will definitely cause a lot of problems, if they don't reveal themselves and make decent watermen the thing could get out of hand.
Even though Atletico Madrid has recruited quite a lot of players this summer but has not shown any changes for the better from last season, it can even be said that they started the season badly. I think there is something wrong with the strategy and formation created by the coach so the coach needs to fix it while it is still early in the season so it is not too late to fix everything because Real Madrid and Barcelona will continue to show their best performance so if Atletico Madrid experiences a setback it will make them happy because they have lost 1 competitor in the trophy hunt.
Barcelona and Real Madrid fans might be happy about Atletico Madrid's decline in performance, having lost a rival in the title race. However, I don't think La Liga fans are happy about it. This will make La Liga even less competitive and exciting.
Atletico Madrid hasn't been very active in this transfer window. They've only made a few additions. They brought in several top players last season, but they needed time to adapt, which is the main reason Diego Simeone is so supportive. They've been leading this season with confidence and a strong squad. However, the results in their first two matches have been quite surprising. I think the problem now lies with Diego Simeone's tactics, as he is the one primarily responsible for the team's slump.
