Supplementing an opening period double from James Clarke, Jonathan Afolabi, Declan McDaid, Kris Twardek and Adam McDonnell also rattled the opposition net to give the seven-time champions a safe passage into the last eight.

It seemed like only a matter of time before the Gypsies broke the deadlock – even allowing for the torrential downpour that descended upon the Phibsborough venue for the duration of the contest – and their opening goal duly arrived on 18 minutes when Clarke fired home from close-range.

This season’s FAI Intermediate Cup winners, Rockmount (for whom Roy Keane began his footballing journey as a youngster in Cork) suffered a further setback on the first-quarter mark.

Following a pull-back by Danny Grant, Afolabi calmly slotted the ball into the bottom left-hand corner for a second Bohs goal.

After McDonnell and James McManus went agonisingly close to finding the net, the hosts ultimately brought a 3-0 cushion into the interval when Clarke confidently doubled his tally in first-half stoppage-time.

Introduced on the resumption along with Ali Coote, McDaid added his name to the scoresheet in the 56th minute for the rampant Gypsies with a neat finish off his left foot.

McDaid’s fellow substitute Twardek added a fifth after Rockmount netminder David Browne couldn’t hold onto the greasy ball and McDonnell then completed the scoring five minutes from time with a spectacular strike off a free-kick from an acute angle.
