Ten goals were scored in an 8-2 win for Everton over Southampton in which nine different players found the back of the net.
Visitors Southampton had gone 2-0 up through Christoph Klarer and Marcus Barnes. But Anthony Gordon struck a quickfire brace to take his tally to five in his past three matches and make it 2-2 at the break.
In a crazy second half, Matthew Foulds, Harry Charsley, Alex Denny, Antony Evans, Morgan Feeney and Manasse Mampala all got on the scoresheet.
Everton's Evans also assisted three goals as unbeaten Everton secured a dominant first win of the Division 1 campaign.
David Unsworth's side move up to fifth in their title-defending season, while a third consecutive loss for Saints leaves them second from bottom in 11th.
