Of the realistic choices, I do like Deschamps. History with the club and has good relations with French players which is always useful. They have a lot of young talent you would like to lure to this club.
I have to see the rest of Lazio's campaign but Inzaghi would be in my top 3 probably. If he finishes top 4 in Serie A and wins the EL, I think he has to be a top choice.
Giampaolo from Sampdoria is probably in my top 5 but behind those two by a fair margin.
I don't think Sarri has Juve DNA. He is a fine coach tactically but I don't like his temperament.
Basically for me, the most realistic international choice is Deschamps. The most realistic and probably best domestic choice is Inzaghi.
If I were to choose from any coach, I would take Simeone. He shares the same temperament problems as Sarri but at least it's worth it in his case. He has shown he is capable of competing with Barca/Real with lesser quality.
