Eden Hazard scored two goals and made another to help Chelsea thump London rivals Arsenal in Baku and win the Europa League.
Olivier Giroud sparked the landslide against his former employers in the 49th minute before Pedro put a second past retiring Gunners goalkeeper Petr Cech.
Alex Iwobi pulled one back in between Hazard’s double but Arsenal faded horribly after half-time and, having finished fifth in the Premier League, are now consigned to another season outside the Champions League.
Chelsea’s triumph brought them their fifth European title and their first since they won the Europa League in Amsterdam in 2013.
An emotional Sarri celebrated with his players on the pitch, but his future remains in doubt despite ending his first season at Stamford Bridge on a successful note.
