Next Sunday's All-Ireland SHC semi-final between Cork and Limerick is expected to draw in the region of 70,000 spectators to Croke Park.
GAA headquarters also hosts the other All-Ireland SHC semi-final between Galway and Clare on Saturday, which should attract an attendance of around 50,000.
Speaking to the Limerick Leader, Limerick manager John Kiely insisted that his young side wouldn't be fazed by the occasion.
"Support is fantastic and it was great last weekend (against Kilkenny) to have all the support there, but the numbers travelling to the match don't concern us and that's outside of our area of concern," he said.
"It's up to the county board to deal with - we just hope the people that come to support us are fully behind the team and if we are to judge on this summer they have given us fantastic support and I am sure they will again on Sunday.
"A lot of our lads have played in Croke Park with minors, colleges and club All Irelands and the more senior lads have played there before so it's just another ground."
