It is Naismith’s show as Everton thrash Chelsea
Naismith came on for the injured Muhamed Besic early on and headed in Brendan Galloway’s cross before rifling in a shot to put the Toffees 2-0 up.
Chelsea responded when Nemanja Matic scored with a superb 30-yard effort.
However, the visitors struggled for chances and Naismith slotted in a late angled strike to complete his treble.
Chelsea’s tally of four points from a possible 15 means they have made their worst start to a top-flight season since 1986.
The Blues lost only three games on the way to the Premier League title last season – but after losing three already this campaign they could be 11 points behind Manchester City if their rivals beat Crystal Palace on Saturday.
“It is better not to look at the table,” said Chelsea manager Jose Mourinho. “For me it is the first time I look and see my team in that position. I don’t look at the table, I look to players, the training session we have and the matches.
“Our next match in the Premier League is against Arsenal and we are candidates to win.”
