Both Dean Carpenter and Darren Clarke have proved themselves capable of tackling the challenge provided by the biggest Hooped side in Irish amateur football.
The Collinstown duo were both key as the LSL side defeated FAI Junior Cup champions Sheriff in the Leinster Junior Cup final in May.
Indeed, Carpenter enjoyed success against all manner of Hoops in the Tallaght Stadium in recent years, being part of a side that defeated Sheriff back in 2015 and a team that scalped Shamrock Rovers at the ground.
However, the duo were not celebrating victory as the biggest Hooped side of them all came to Tallaght yesterday.
Celtic came to town and fielded a strong side to put nine past Shamrock Rovers over the weekend.
Both players would be upset at the manner of the reverse, but upon reflection may be content they managed to play against the massive club and some household names.
Not only is playing against Celtic a dream come through for a host of young, amateur and indeed pro players in Ireland, but the fact both got onto the pitch suggests they have been impressing on trial at Shamrock Rovers.
Carpenter, Collinstowns captain last term, started the tie and was handed the number 2 shirt. The left back was on the field for 66 minutes before he was replaced by Conor Gleeson.
Pacey winger Clarke got the majority of the second half after replacing Darren Meenan on 46 minutes.
The teams were as below:
Shamrock Rovers: Kevin Horgan; Dean Carpenter (Conor Gleeson 66), Tim Linthorst (Sean Callan 59), Sam Bone (Darragh Gibbons 77), Cian Collins (Conor Fitzharris 66); Darren Meenan (Darren Clarke 46), David McAllister (Richie English 66), Aaron Bolger, James Doona (Kenny Cunningham 46); Michael O’Connor (Dean Dillon 46), Sean Boyd (Eric Abulu 77).
