To all of you saying Sarri doesn't make sense, have you considered that our management simply wants a more attacking coach to attract new fans? Agnelli has been trying to grow the Juve brand, there's no doubt about that. The logo change, the signing of Ronaldo, and next season's home jersey are clear examples. Perhaps the next step is to change our style of play and from that perspective Sarri makes sense. Guardiola, Klopp and Pochettino would've been the preferred options but they're unattainable so we're settling for Sarri.
attracting fans and growing the brand with a chain smoker, bigot, tracksuit wearing, homophobic coach? why not
also,
sarri and hyper attacking beautiful football is simply a myth. sarri came close to winning the scudetto with napoli because he fixed napoli's defense (or he just got lucky with koulibaly, it's a matter of approach, really). his empoli was a rather defensive team, and so is his chelsea. he's a very good coach, but those who expect all guns blazing kind of attacking football from him might not be prepared for the unavoidable disappointment.
napoli's goal scoring record from 2012/13 to 2018/19, along with goals conceded and league finishes:
sarri years marked. also, please note that their best scoring year resulted in a 3rd place, but their point record arrived when sarri finally fixed the defense, at the expense of their goal scoring record. please also note that napoli were outscored by both juve (86 goals) and lazio (89 goals) in '17/18, and by roma (83 goals) in '15/16, while napoli scored the most goals in '12/13, were second to juve in that regard next season, and they were just a couple of goals behind juve (72) and lazio (71) the year before sarri took over. napoli always played attacking football, that was part of their philosophy way before sarri took over. also, i don't think that you consider either allegri or inzaghi an attacking coach, despite both of their teams outscored sarri's napoli in sarri's special season.
as for his only chelsea year, which is not a huge sample indeed:
i didn't bother too much about showing you the obvious: he couldn't improve on last year's team a bit, and even his team's defensive performance left a lot to be desired.
and you don't want me get started on his empoli which played a possession based, rather defensive footie. sarriball is short passes and possession, not all-out attacking.
so we might just drop that "omg sarriball = attacking :tuttosport" talk for good, shall we

sorry to disappoint, but he's not so influential as some might think, and also let me reiterate this:
his best league result arrived when he finally fixed the napoli defense. i give him that, his '17/18 team was a special one, and we were lucky to have a well prepared coach who accepted the challenge.
