Ferguson is in interim control after Marco Silva was sacked following Wednesday's Merseyside derby thrashing at Liverpool that had left the Toffees in the relegation zone. And Everton banished their recent struggles to run out fully deserved winners on a thunderous occasion illuminated by the former striker's wild celebrations. The Scot raced down the touchline when Richarlison headed Everton in front from Djibril Sidibe's cross after only five minutes, then swung a ball boy around in the air when Dominic Calvert-Lewin took advantage of slipshod Chelsea defending to increase their lead four minutes after half-time.
