Yes. The previous time people thought it was "luck", Atleti have won the league. It is Simeone and his team, and people should have acknowledged it a long time ago.
They still have a lot of exploitable potential in attack with the likes of Jackson, Vietto and both Torres guys who have underperformed. Right now, their threat in attack comes only from Griezmann mostly with occassional bursts of Carrasco, Correa and the recent joker, Thomas. Moreover, they are more than dangerous in the long run - I mean in two/three years time, for instance. Add Koke, Saul, Gimenez, Kranevitter, Oblak and Lucas Hernandez to already mentioned guys and there is a great team with players just at their peak.
