Simeone was finished 3 years ago. Zero ideas, zero results. I don't know what needs to happen for Atletico management to think about sacking him. I think the problem is him. Atletico have a good squad, they can afford to buy top players, Simeone is the most expensive coach in the world... where are the results? It is clear to the naked eye that Atletico is playing worse from season to season, even their signature defense is no longer good. By the way, in the next round Atletico plays Villarreal, again minus 2 or 3 points? 
I just checked and saw that Atletico Madrid spent 175 million euros on signings this summer. But still 0 positive result.
They are just throwing their money away. Sad to see it...Everything has an end and Simeone also must go soon. They should sign a manager who will build a solid attacking system. They need to get more productive. Only then they can be more competitive in the La Liga.
