I don't think we'd have ever been able to take him. Allegedly, he's said he would only take charge of clubs who he used to play for. Hence why Inter Milan could be his next destination in the future.
Even if it was a possibility though, my one real gripe with Simeone is his style of play. I have no doubt we would become a dogged, resolute side with him, but I don't know if he is capable of playing attractive football.
Baring in mind he has bought a lot of attacking players over the last 4 or 5 years and he hasn't been able to maximise their potential. Mandzukic, Torres, Cerci, Lemar, Gelson Martins, Baptistao, Jackson Martinez, Kalinic, Vietto, Carrasco, Gameiro, Vitolo, re-signing Diego Costa, question marks over Morata...
His track record in this sense hasn't been spectacular.
He's still adopted the same backs-against-the-wall, efficient counter-attacking philosophy that he had when Atletico didn't have as much money to spend like they do now.
I can't speak on behalf of every single Arsenal fan, but for me, I want to be entertained watching my team play. Especially as we pay amongst the highest ticket prices in Europe. His defensive resolve would be welcome. However, I don't know if I could stomach watching dull football every single week for multiple years. That's not the direction I want us to go in.
I'm happy with that. Currently, I don't see Emery delivering that for Arsenal fans...but maybe he will?
