Sean O’Mahony’s manager Alan Craven said his unfancied side's extensive homework paid off in spades after they marched into the AIB Leinster Club SFC semi-finals.

The Louth men held off a late fightback from 14-man Sarsfields in Drogheda on Sunday to make the last four with a 1-08 to 0-08 win.

With the sound of his team's celebratory singing bouncing off the halls of the dressing-rooms, Craven was left overwhelmed.

"I'm lost for words at the moment," he told RTÉ Sport.

"In fairness we did our homework. We realised Sarsfields' pedigree, realised what they bring to the game.

"We managed to get some footage of some of their recent performances, very impressive. I think we got our match-ups right defensively."

Having nullified their opponents early on, Stephen Fisher’s goal seven minutes after the break pushed Sean O'Mahony's into a a 1-6 to 0-2 lead.

Gary White's dismissal soon after that looked to have crushed all hope Sarsfields, but they gave it a real go in the closing stages, getting back to within a point before O’Mahony’s finished with late Ben McLaughlin and Stephen Kilcoyne scores to close it out.

For Craven, the gameplan worked to perfection.

"They're a high-scoring team," he added. "We set ourselves a target of keeping the scoreline very low in the first part of the game.

"We did set up I suppose ultra defensive but we don't have the pedigree, the history or tradition that some of these teams have so caution was our first approach. But we're elated, delighted with the result."
