David Luiz hailed Maurizio Sarri's "amazing" impact on Chelsea following the glittering 4-1 victory over Arsenal in the Europa League final in Baku.
Former Napoli boss Sarri lifted his first major trophy after Eden Hazard's double and one apiece from Olivier Giroud and Pedro torpedoed Arsenal's bid to squeeze into next season's Champions League.
Hazard revealed the match is likely to mark a "goodbye" to the Blues and doubt also surrounds the club's head coach, Sarri having been heavily linked to the vacant Juventus post in recent weeks.
