Too early for this discussion.
End of season is probably the earliest we discuss this unless everything falls apart before the World Cup.
Only way we sack Simone is if he barely makes Top 4, with no continental advancement (even if it's just Europa League) and a bad showing at the Coppa.
I trust that Simone will deliver in the cup and the top 4 will be safe, but we'll struggle to compete for the Scudetto, especially if any rival team manages to get serious about it. I think that'd be Juventus and it'd be Milan who will be chasing them, not us. Unless things change.
In football at the moment there are two dominant "schools" now, and the Italian one has been dissolved by its own accord for no reason. Nothing about being outdated, it was just a decision that the teams collectively took and they're now a hybrid system rather than one that focuses on its strengths.
We have the German school, with its high pressing and full intensity.
We have the Spanish school with his highly technical approach that smothers teams with possession.
Obviously this is not set in stone but they are the generic schools of football that dominate today. You still have high pressing in Spain despite dominant possession.
One is highlighted by Jurgen Klopp and the ideal is highlighted by Josep Guardiola.
Getting a coach of that school would be beneficial if that's the direction we want to go for but it takes a lot more.
Teams like Bologna, Atalanta, Torino and Verona are very to extremely high pressing teams. Italian clubs in general utilize high pressing to a larger degree than the PL or Ligue 1, but it doesn't really suit the teams in Europe because of the way these teams are preparing against a lot of their competition who aren't willing to press high and prefer to sit back.
We have to decide which approach is best suited for us. I'd go with a German coach, directly to the source. The Spanish model needs a special breed of players that are extremely capable on the ball.
Ivan Juric has done a great job in his last two jobs and he should be a candidate, but I'm not confident with us taking that risk. We're not a good place to elevate a coach's level. We need something ready.
The option of Simeone is ideal. We are a team that is driven by grit and nothing enforces it more than Cholo. I'd still welcome Mourinho back as I think it's established by now.
These are remnants of the Italian school, but with a more conservative approach due to the type of football the opposition now has.
But if we want to take a jump to "modern football", we need to decide between Germany and Spain and stay the course.
