It's 29 years since Pete Mahon's St Francis went all the way to the FAI Cup final.

They were the first amateur side to make the decider in over 50 years. No club has emulated the feat since. 

That's the scale of the challenge facing Leinster Senior League outfit Crumlin United tonight when they square up to Premier Division heavyweights Bohemians in their postponed quarter-final at Richmond Park.

The game has been moved to the home of St Pat's from Crumlin's Pearse Park and has gone somewhat under the radar, with all three other last-eight ties done and dusted and the draw for the semi-finals already made.

This clash was put back due to Bohs' pair Danny Mandroiu and Darragh Leahy being called up to Stephen Kenny's Republic of Ireland Under-21s.

The two clubs therefore know there's a significant carrot waiting in the next round: the winner of this one will host Shamrock Rovers.

Understandably, most are anticipating a mouthwatering Dublin derby in that semi - Bohs are of course overwhelming favourites to get past Crumlin tonight.

Martin Loughran's men may be the underdogs, but they have a commendable pedigree and enough footballers with high-end experience to command respect.

They've beaten two other amateur teams to get this far - Malahide United and then Lucan United - and will see this one as a free hit.

Midfielder Craig Walsh first came to prominence on Sky One's 'Football's Next Star' programme back in 2010 as one of the young talents competing to win a professional contract with Inter Milan. Spells with Shamrock Rovers, Longford Town, Bohemians, UCD, Shelbourne and Bray Wanderers followed in the LOI so he comes equipped with plenty of experience. 

Striker Dean Kelly won a Premier Division title with Shamrock Rovers back in 2011 and also played for St Pat's, Shels and Bohs.

The skipper Thomas Hyland is another who was on the books at the Hoops and Longford Town while Jake Donnelly was with Shels up until 2015. There's ability in the ranks.

Two years ago Bluebell United gave Shamrock Rovers a right rattle when they met in the quarters.

Bluebell similarly had a vein of quality, experienced players - including former Republic of Ireland international Keith Fahey who missed the Rovers game due to suspension - so Crumlin will feel they can stand up to Keith Long's men and really do themselves justice.

Last season they strolled to the Leinster Senior League Senior Division title. They also dumped Finn Harps out in the the second round back in 2016.

"It's a great draw. It's great for the club and great for the area," Loughran told RTÉ Sport after they pulled Bohs form the hat.

"It's something at the start of the season, you always try to get into the FAI Cup. We’ve managed to do it a few times over the years. We have beaten Finn Harps, Shelbourne and Wexford Youths, so we have done okay in it.

"The lads really like this competition."

Anything other than a Bohs win would be a monumental upset, but Crumlin have enough in them to let their vaunted opponents know they're in a game.

They'll go to Inchicore under little pressure with nothing to lose.
