And it would be fair to suggest that Declan Devine will be glad to see the back of Mick Cooke and his men as the Boynesiders had already dumped the Candystripes out of the EA Sports Cup semi-final a week previous.
Drogheda doubled the dose with the Brennan brothers producing the goals on either side of half-time as the home team huffed and puffed in front of a disappointing attendance.
But Derry can have no complaints with this defeat and, indeed, they were the authors of their own downfall yet again.
Simon Madden and keeper Ger Doherty appeared to get into a mix-up in the Derry defence and when O’Brien’s shot had been parried by the latter, Gavin Brennan rose high to head the lose ball home from close range.
It got worse for the Devine’s side after the break when Shane McEleney clearly and foolishly impeded Ryan Brennan, pushing the midfielder in the broad of the back, as he raced into the danger area.
A well placed referee, Alan Kelly, had no hesitation in pointing to the spot and Ryan Brennan drilled home the spot kick.
