Selsey were smashed for six as East Preston showed no Christmas cheer in an SCFL Division One south coast derby.
Joe Clarke got the Blues off to a flying start with a goal inside the first 60 seconds.
But after that it was all East Preston, with EP scoring five without reply.
Lukas Franzen-Jones bagged a hat-trick, while Jared Rance and Dan Huet each got themselves on the scoresheet.
Selsey had a brief moment of cheer when Jake Ebling scored with five miniutes to go.
But Huet popped up again as time ticked down to condemn Selsey suffered their heaviest league defeat of the season so far.
The loss sees Steve Bailey’s young side drop into the bottom half of the table for the first time in a month.
But they will have chance to bounce back on Monday, as the Blues host Storrington at the Bunn Leisure Stadium (11am).
The visitors have been in good form of late, unbeaten in nine and last losing in the league away at Seaford at the end of October.
Bailey will be hoping his charges can put the bad result behind them and get their season back on track.
When the two teams met earlier in the season it was a seven goal thriller.
Joe Warner and two goals from Matthew Searle put Storrington in the driving seat.
But Selsey matched them all the way, with Ryan Chittock and Joe Clarke, as well as an own goal seeing the Blues draw level with 20 minutes to play.
However, a late strike from Warner saw Bailey’s side come out worse off in one of the matches of the season so far in Division One.
Late goals and a lack of consistency have haunted Selsey this season and stopped them from making a serious push up the table.
The curse struck again against Steyning Town just before Christmas, pictured right.
The visitors were gifted a fourth minute lead as a misplaced pass was intercepted by Charles Romain, who went on to finish.
Howard Low had the home side level on the half-hour, before Selsey took the lead for the first time four minutes before the break through Tom Groom.
But a late strike from Lewis Levoi with just four minutes to go meant that the Blues had to settle for a point, for the sixth time so far this season.
With up to four games in hand on sides around them, there is still a chance of a Selsey surge up the table as the season moves into its second period.
