The manager of the 2014 Clare Senior Football champions is warning they must produce their best performance of the season if they're to book their place in this years decider.
Cratloe will go up against holders Miltown in a battle of the last two championship winners.
Cratloe boss Colm Collins says their form so far this year won't be good enough for victory on Sunday
The other semi final is also down for decision this weekend as last years beaten finalists Cooraclare square off with 2012 champions Kilmurry Ibrickane.
Cooraclare have taken the scenic route to the last four, recovering from a heavy defeat to Miltown with wins over Wolfe Tones and Doonbeg.
Manager Ger Lawlor says they were forced to be very honest as a squad following that Round Two loss.
