Moyes enjoyed a fine 11-year reign at the helm of Everton and it was widely expected that the Scotsman would be handed a warm reception by the Toffees' faithful when their side squared off against the Black Cats at the Stadium of Light.
Surprisingly though, Moyes was at the end of some vile abuse from the Everton supporters throughout the clash and some even chanted 'You're getting sacked in the morning' at the direction of their former manager who saw Ronald Koeman's side salute 3-0 on Wearside.
Below are a selection of Tweets from fans who felt the Everton behaviour towards Moyes was disrespectful:
Real lack of class from the Everton fans singing your getting sacked in the morning to Moyes, considering he signed half the Everton squad.

Everton fans singing to Moyes "You're getting sacked in the morning" classy as ever to an ex manager that gave his all for their club.
