I'm not really a fan of Perisic, but our 'Neymar/'Hazard' player is surely going to be Griezmann.
Mourinho is simply building his team in the configuration he is most accustomed to. In the attacking positions that generally means a classic #9 with decent hold-up play (Drogba, Milito, Ibrahimovic, Costa - Morata/Lukaku/Belotti?), a wide forward who stays high up the pitch (Eto'o, Ronaldo, Hazard - Griezmann?), and, to compensate, a more-defensive hard-running wide player tucked in on the other side (Pandev, Di Maria, Willian - Perisic?).
