It was another heartbreaking setback for the 'Mayo for Sam' campaign today.

An encouraging first half from Mayo buoyed hopes, but it all came crashing down int the second half with Dublin netting three times to finish with a comfortable victory margin of 3-14 - 1-13.

Here's a taste of some of the reaction on Twitter:

Is there any team as terrified of success as Mayo? Inevitable collapse. #DUBvMAY #GAA #COYBIB
