Con OโCallaghan v Sam Callinan
In the full-back line, Callinan looks like a man at ease in his surroundings.
Even though he only made his championship debut a month ago, manager Kevin McStay said that he has no worries about the 20-year-old from Ballina Stephenites producing the goods.
Many will believe that coming up against one of the greatest players that the game has ever produced in Con OโCallaghan might be a step too far.
But Callinan has already moved from his comfortable number four position to centre-half back earlier this year to pick up Seรกn OโShea.
Tasked with the second biggest marking job that day, the young UCD student played a stormer by keeping OโShea scoreless from play.
The issue with Dublin is, we donโt exactly know where theyโre at in this moment in time.
In their last match they waltzed through Sligo, with OโCallaghan producing a stellar performance at full-forward.
By the 55th minute his job was done and he was happily withdrawn to save his energy for the next day out.
But are they at the level they hoped they would be at?
This match-up will be a key factor in the Rest v Momentum debate.
Itโs going to be a huge job for Callinan to keep OโCallaghan at armโs length, but not an impossible one.
