The person who should really be under criticism is Igli Tare. I headed over to the Transfer Market site and looked over his list of significant-- meaning, not Primavera or Salernitana-destined-- purchases over the past three seasons: it's a pretty dismal list.
- Francesco Acerbi: A
- Manuel Lazzari: A
- Joaquin Correa: B+
- Gonzalo Escalante: B
- Pepe Reina: B
- Jean-Daniel Akpa Akpro: C+
- Jony: C
- Milan Badelj: C
- Romulo: C
- Wesley Hoedt: C
- Silvio Proto: C
- Mohamed Fares: C-
- Andreas Pereira: D+
- Vedat Muriqi: D
- Mateo Musacchio: D
- Bobby Adekanye: D
- Riza Durmisi: D
- Denis Vavro: D
Out of eighteen players, he only wound up with two difference makers. People might quibble with me regarding Correa, but for all of his "highlight reel" flourish, when you boil him down he only scores once in every five matches, which is a pretty terrible record. I'm not proposing he be sold or anything-- I'm merely justifying his not reaching an "A-".
And it's not as if this plethora of players weren't given chances: Inzaghi provided each of them with a significant number of run-outs-- they simply failed to make much of an impact. And if you look at essentially all of them who have since departed-- take Jony, for instance-- their market value has continued to decline, even after switching clubs, and having a brand new coach.
All of this sums up Tare's Lazio sides well: three or four superstars-- Luis Alberto, Sergej Milinkovic-Savic, Ciro Immobile, Franceso Acerbi-- surrounded by a fairly mediocre, error-prone cast. I think even mid-table clubs like Sampdoria and Sassuolo have better auxiliary players.
