Cowfold will be looking to finally clinch the Sussex Intermediate Cup having booked their place in final of the competition for the third time.
Beaten finalists twice and with numerous quarter and semi-finals defeats to their name they overcame Sidlesham 3-2 to set-up a showdown with local rivals Roffey in this year’s final.
The hosts did have a good chance of their own when Ben Hands was sent clean through only to scuff his side-foot shot wide.
Some poor defending saw Sids take the lead on nine minutes as Thomas Jefkins met a square pass with a fantastic strike to find the bottom corner.
Cowfold pressed for an equaliser and on 27 minutes the Sidlesham keeper spilled a shot and then forced Chris Spiers’ effort over the bar.
Luke Parsons headed against the bar and Hands’ follow up was again pushed out for a corner which was then cleared off the line.
Two minutes into the second half, Spiers’ delightful lobbed flick found the feet of Hands and he smashed home to make it 1-1.
Cowfold’s dominance was reward just before hour as Spiers played a ball through for Greg Brabon whose unerring finish put them ahead.
Sidlesham, who are third in Division 2, however showed their capabilities as a lapse of concentration by Cowfold saw them snatch an equaliser in the 86th minute as John Philips notched.
Cowfold won the game with just 70 seconds of added-time remaining as Hands ran to the byline and drove a ball low across the six yard box where Nigel Smith side-footed home.
Cowfold assistant manager Paul Curtis said: “It was a fantastic team performance which has got us to a our third county cup final this time against local rivals Roffey who put out run away league leaders Bosham with an identical scoreline.
