Barca busted, Madrid Mbappeless - Atleti have the best squad in Spain
Now, they are in a fantastic position to actually defend the championship and establish themselves as the most dominant force in the country following the summer transfer window.
Los Colchoneros have had a fantastic window, while closest rivals Real Madrid and Barca have had a disastrous one.
Not only have Atletico brought back their prodigal son Antoine Griezmann, but in the process they have weakened Barca's forward options.
On deadline day, the World Cup winner completed a sensational loan move back to the capital, where he enjoyed the best playing days of his career so far.
Yes, Griezmann did not perform well enough for Barcelona, but if there is any man who can get him back to his best, it is Diego Simeone.
Barca, well, they replaced the Frenchman in underwhelming fashion with Luuk de Jong.
A year ago, the Blaugrana made the decision to allow Luis Suarez to leave for Atletico, and he helped fire his new club to the title. Barca may regret doing the same with Griezmann.
The biggest hit Barcelona have taken this season has naturally been the departure of legendary forward Lionel Messi, who has joined Paris Saint-Germain.
As for Real Madrid, well, they put all their eggs in the basket of Kylian Mbappe.
PSG refused to negotiate despite a reported €200 million offer on deadline day, leaving Los Blancos without a big money signing, again.
Though Saul Niguez left for Chelsea, they are well-stocked in the midfield department.
Atletico's squad depth
Diego Simeone has deployed a three-man backline for the start of the new season, and that should continue with Stevan Savic, Jose Gimenez and Mario Hermoso in defence.
Kieran Trippier should be asked to play as a right wing-back, probably with Yannick Carrasco on the left.
In the middle, Marcos Llorente is available to partner Koke.
It is in attack that Simeone now has a plethora of options, and expect Griezmann to come in perhaps in the number 10 position behind Suarez and Angel Correa.
Unfortunately for Joao Felix, the acquisition of Griezmann means he will fall down the pecking order.
