Steven Naismith scored a hat-trick as Chelsea's struggles continued with a third loss in their opening five league games following a defeat at Everton. 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. "Our next match in the Premier League is against Arsenal and we are candidates to win."
