7 Years - 45 games unbeaten - Dublin go down fighting to Mayo. A first Championship loss for Brian Fenton. What an era it's been for the Dubs. A first win for Mayo over Dublin in Championship in 9 years.

Fair fucks to @MayoGAA brilliant stuff the heart and courage they have shown in the 2nd 35min was brilliant, @DubGAAOfficial there for the taking or is it heartache again

Interesting watching @DubGAAOfficial implode in added extra time with black cards and lack of scores. Not the steely operators they used to be. Congrats to @MayoGAA on a deserved win. Hoping they push on now and nail the final. #mayovsdublin #gaa #mayo #mayoforsam

Surely there is no stopping @MayoGAA now. Even with big players out they dug deep when it mattered. Serious performance. @tommy_c99 took the game by the scruff of the neck. #mayo4sam #gaa #intensity

Today is Mayo’s day and congrats to them. But it’s also the end of the greatest run in the history of Gaelic Football. Almost certainly never to be matched. The greatest team of all time ends it’s reign. They gave us everything. #dubvmay #gaa #coybib

I really hate to be playing Mayo in the finals. They've waited so long. But not that much. Sam's coming west.#GAA
