Colchester United's U23s fell to only their second defeat of the season on Monday afternoon, as Watford ran out 3-0 winners at Vicarage Road.
It was a closely fought encounter for the first half an hour, before the home side took the lead on 33 minutes from the penalty spot.
Folivi was fouled in the area, and it was left to Djedje to fire home the penalty past Dan Wilks and put the Hornets 1-0 up.
They then extended their advantage on the stroke of half time, as the lively Folivi embarked on a run down the left, before scoring from just inside the U's box.
Two ahead at the break, the home side then kept the U's at bay, before further extending their lead with just under twenty minutes to go.
Eleftheriou crossed from the right hand side and it was nodded down by Djedje to find fellow goalscorer Folivi to wrap the game up for Watford.
