In fact, Real Madrid, which basically brought in great players like Mbappe and several other potential young players, in reality Real Madrid still failed to start this season perfectly. So, if a team like Real Madrid can also fail, especially a team like Atletico whose quality is basically below Real Madrid, then of course Atletico can also fail even though they managed to bring in great players in the last transfer market.
I don't understand what you mean by "Real Madrid still failed " sorry, but could you please make some specificities on how they failed??
Mbappe got signed to the club and, in just one game to wrap up the competition, they won the League already. AFAIK, Real Madrid is one of the best teams in the Spanish league, even in other competitions as well. Do you understand what it means to have Rodrygo, Bellingham and mbappe as a team's standard and forward players?
But even so, of course Real Madrid and Atletico still have the same chance to be candidate teams for the trophy this season.
La Liga isn't a competitive league.... Not as competitive as the English Leagues. What do you think is the reasons why Nicholas Jackson and the rest had a hard time in the premiership? Again, that's not enough to belittle Madrid!
