Dublin City 0 Derry City 2
Rock bottom Dublin City look all but doomed after this damaging defeat.
Dublin were a mess from the start with four new signings in a 3-5-2 formation never working.
They fell behind on 17 minutes when Gareth McGlynn’s left wing free-kick was turned into his own net by the unlucky Tony O’Connor.
The second goal came four minutes into the second half.
Peter Hutton stepped over a free-kick 30 yards out and Alan Murphy's fierce low shot deflected off the wall to wrongfoot Robbie Horgan.
