Atletico Madrid haven't made much change in their squad for this season. This is a usual thing for Atletico Madrid so I'm not surprised with that. However they have still made a good progress compared to last season. Because this time Atletico Madrid started the season really strongly. Especially that win by 7-0 was brutal.

Simeone is actually using his usual system so I guess it is related to the players now. They seem much more concentrated on their game at the beginning of the season. This is a really important thing for Atletico Madrid to keep up with Barcelona - Real Madrid duo this time.
Do you think they can maintain their claim for the title for a long time?
The solution to the problems facing most teams is not always player signings and most times club go on to make panic transfers that turn out to be ineffective. The manager is fully aware of the strengths and weaknesses of his team. Atletico Madrid didn’t make many signings as many other clubs in Europe did. It looks like Simeon has found the solution as Atletico Madrid are doing well and better than they finished last season.
