Willian has further fueled talk of a rift with Antonio Conte while celebrating Chelsea's FA Cup win.
The Brazilian replaced Eden Hazard - scorer of the only goal - in the 91st minute, touching the ball just five times, as the Blues made amends for last season's defeat at Wembley.
Willian has scored 14 goals and assisted a further eight across all competitions this season despite not nailing down a regular starting spot.
Amid reports of tensions between the pair, Willian has hidden Conte with three trophy emojis when posting a squad-wide image of Chelsea celebrating beating Manchester United on Saturday.
Ahead of the FA Cup Final, ESPN Brasil asked Willian about Conte's relationship with players and the midfielder reportedly responded: "Oh boy, do you really want me to tell you? ? Let's save it for the next interview."
Jose Mourinho was keen to be reunited with Willian last summer but Chelsea refused to negotiate a transfer with United.
