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. 
The biggest win I've seen for Atletico in their last few seasons 
Let's hope it's not a fluke and their schemes with the current players are what Simeone is hoping for because if they end up struggling to score again then I'll be a bit disappointed after that big win.
On the other hand, it's true that for the start of this season they were also pretty good in terms of performance because usually they are very bad but it seems that for now they have found the missing puzzle especially for their attacking line.
Barcelona outcast duo Depay and Griezmann are finding their form again this season.
