Adam Hinshelwood branded Worthing’s 6-0 home hammering at the hands of Hornchurch as ‘unacceptable’.
The hosts capitulated in front of their own support at Woodside Road after captain Darren Budd was forced with a fractured fibula on 52 minutes.
Chris Dickson went on to hit a hat-trick while Ronnie Winn was at the double before substitute Charlie Stimson rounded off the scoring.
All of those strikes came in the final 34 minutes as Worthing fell apart.
The way in which his side unravelled left manager Hinshelwood worried.
And the former Brighton defender believes the club’s supporters have every right to be angered by what they saw.
He said: “I think we’ve absolutely gifted them all six goals so that is cause for concern.
“After the first goal the confidence just drained out of the side.
“They exposed our defensive frailties that we showed last season.”
