Drogheda United cruised into the eircom League Cup quarter-finals with a straightforward victory over Shelbourne at Tolka Park.

Drogheda boss Paul Doolin retained just three of the players who started last Friday's Premier Division match, although eight of the line-up had played in first-team colours this year.

Anto Flood, James Keddy and Greg O'Halloran were the only notable absentees from the Shels team.

The Boynesiders dominated from the start and should have edged ahead on 17 minutes when Jason Gavin screwed his shot wide from six yards.

Then Ibrahima Iyane Thiam waltzed his way through the Shels defence before firing just over Dean Delaney's crossbar.

Tony Grant wasted Drogheda's best chance of the half on 38 minutes when he somehow headed wide from Richie Baker's cross, but it was a case of villain turning to hero just two minutes later.

Paul Keegan rolled a free-kick into the box and Grant reacted quickest to steer the ball past Delaney.

Mikko Vilmunen in the Drogheda goal was called into action for the first time on 52 minutes when saved Max Cream's shot at point-blank range, and the Finn also did well to block Stephen Doran's powerful effort.

In between, Iyane Thiam's shot was clawed away by Delaney.

James Chambers was then foiled by Vilmunen after taking advantage of Gareth Whelan's error, and it proved a costly miss as Drogs substitute Shane Robinson steered home Drogheda's second goal a minute later, despite Alan Murphy's efforts to block the ball on the line.
