Atletico Madrid didn't make many changes for this season so I don't think they will do much and what happened now is surprising but for me this is only temporary because no matter what they are a team that should be watched out for even though they won't be able to disrupt the competition between Real Madrid and Barcelona so maybe Atletico Madrid will only compete for the top 4 again like last season.
It is noted that Atletico Madrid has added 10 players to its squad in this summer's transfer market, so I think they have made a lot of changes, but that is not the problem, because I think the problem lies with Simeone, the tactician has run out of ideas with Atletico and the signs are clearly visible in their last 2 matches, yes indeed in terms of competition they are still considered capable of competing for at least the top 4 but for the title they will not be able to compete with Barcelona and Real Madrid. so in this case the management must be brave to take risks by immediately thinking about changes in the coaching chair if their target is the title but if the target is only to play safe then use Simeone until retirement.
