Well hands up who saw that coming?

If you have your hand up, I don't believe you!

Outgoing champions Dublin have lost an All-Ireland quarter-final for the first time since 2009, but Galway really went out and earned that victory in the second half.

What a second half by Galway, it looked like everything was stacked against them but with every second-half point that went over, their confidence grew.

Most teams don't play with that level of conviction against Dublin, and Galway have just proved what can happen if you have the belief.

A 0-17 to 0-16 win over Dublin, allied to Armagh's 2-12 to 0-12 win over Roscommon earlier, sees them both advance into the All-Ireland semi-finals.

Tomorrow we will see who joins them in the last four when Donegal take on Louth and Derry play Kerry.

Those games will have to go some to top the drama and excitement of that second half but please do join us to find out!

For now we'll say goodbye on an evening that belongs to Galway.

Cillian McDaid speaking to GAAGO after the match:

"I'm pretty exhausted. It was a great game of football, high-scoring open play. I'm pretty shattered now.

"Dublin are the best team, they've ben the best team in the country for the last 11/12 years, consistently.

"We've spent a lot of time watching Dublin over the last couple of years in All-Ireland finals and we know if we have a full team and we all play to the game plan that we can beat anyone.

"Padraig [Joyce] has been excellent for us over the last five years. We've got our act together and we're proving it now."

The second half that we have seen from Galway is absolutely up there with the best we have seen from them under Padraic Joyce.

The style of football that they played, the energy that they brought, the scores that they got, the turnovers, absolutely unbelievable effort from them.

You have to say that that's not a game that Dublin lost, that's a game that Galway won!

Galway have done it! Incredible!

Padraic Joyce's side outscored Dublin by ten points to five in that second half.

Despite trailing for most of the game, they refused to accept defeat and they kicked some heroic scores in the second half with Cillian McDaid outstanding.

Dublin will wonder how on earth that game went away from them but Galway deserved it on the basis of a fabulous second half.

It's Dublin's first loss in an All-Ireland quarter-final since 2009 and it's the first time in 90 years Galway have Dublin in the Championship! A game that will live long in the memory.

Con O'Callaghan hits a shot wide after Paul Conroy kicks possession away.

Can Galway hang on??

Con O'Callaghan with a free. Dublin back to within a point.

Still two minutes of stoppage time to play of the five that's been signalled.

Oh Johnny Heaney, will Galway regret that wild shot when you should have recycled possession and held onto the ball?

A three-point lead was beckoning there.

Galway have been unbelievable in the second half.

Tom Culhane has nerves of steel and lands a brilliant left-footed point and raises his arm in the air! Could that be the winner for Galway!

Unreal scenes. Dublin are beginning to panic.

Absolute class act Dylan McHugh, he's having a terrific year.

Excellent score.

Johnny Heaney has put Galway in front for the first time in ages!

Croke Park is alive now with the Galway fans rising to salute their team's effort in this pulsating second half.

Dylan McHugh could be that man!!

This is heroic stuff from Galway but Dublin don't look rattled.

Paddy Small has come on for Cormac Costello.

The answer is no, as sub Ross McGarry sends over a vital point for Dublin.

Six minutes to go and it looks as though Shane Walsh is finally having to come off. A fit Shane Walsh could have made a real difference for Galway here, but maybe another hero will emerge.

Game on here with eight minutes to go!

Two quickfire points from Cillian McDaid and Cein Darcy have Galway level out of nowhere!

McDaid has made some impact in this second half.

Can Galway hit the front with eight minutes to go?

Shane Walsh taps over another placed ball from close range and it's a two-point lead again.

Galway won't mind seeing Jack McCaffrey follow Paul Mannion off the field, but it's not as though guys like Colm Basquel aren't excellent replacements!

Con O'Callaghan just plays the game the way he wants.

Had the balance and confidence to skate through and picks his moment to shoot.

John Small claims a mark and floats it over from distance, taking the sting out of Galway who had landed the previous three scores.

It's only Dublin's second point of the second half.

Galway have worked a couple of excellent scoring opportunities and they didn't execute but it's safe to say they're starting to find their form and you can see the huge lift it's given them and their support.
