All-Ireland SFC Quarter-final replay: Tyrone established themselves as serious All-Ireland contenders with an impressive performance that showed neither mental nor physical tiredness in their eighth championship game. In fact, they are only now reaching full potential.

Tyrone came out of the traps early in the first half with a hungrier attitude than in the drawn encounter. They did this while living off scraps of possession as Dublin again dominated midfield, but they used what they got better. Once a foothold was established by Stephen O'Neill's goal, they never let it go, even though Dublin threw everything at them early in the second half.

The penalty was a marginal call, but the right one. O'Shaughnessy knocked the ball away from Seán Cavanagh but followed through and knocked the player to the ground.

Tyrone won here because their big players supplied leadership. Conor Gormley was superb at centre half back, and not only in his play - his presence makes a better unit out of the defence in general. Joe McMahon may yet solve the problems at full back.

Alan Brogan did wreak havoc early on and was an incalculable loss to Dublin as Tyrone reeled off three points in quick succession straight after his departure. Two great saves from Stephen Cluxton ensured a glimmer of hope remained for Dublin at half-time.

Brian McGuigan was again outstanding at centre forward; the break in Australia seems to have done wonders for his appetite .

Owen Mulligan was on fire and, almost unnoticed, O'Neill racked up 1-3.

Mulligan's 1-7 and three points from Brian Dooher shows the over-reliance on O'Neill has finally passed.

Dublin lost because the likes of Paddy Christie was injured and could not play and other senior players like stand-in captain Jason Sherlock failed to perform.

Christie's absence seemed to leave the young corner backs Paul Griffin and Stephen O'Shaughnessy overly exposed to the magnificent Tyrone attack. It was like trying to keep out a flood, and switching players around was pointless as everyone was getting swamped.

Tomás Quinn buckled under the free-taking pressure: a disappointing end to a marvellous season for the young corner forward.

In fact, Dublin can be applauded for keeping the margin of defeat down to just seven points.

Dublin and Laois have not gone backwards. It's just they are unable to live with the top three teams when the pedal really goes down. Paul Caffrey is going to have to find a few players.

Darren Magee came in and won a lot of clean possession but Dublin did not have options like the weaving patterns from the Tyrone forwards.

The interval, mercifully, calmed down any chance of matters boiling over and also gave McGuigan a chance to recover from a serious-looking collision. As it turned out, Tyrone needed him.

The resolve Dublin have shown this year - coming back and not wilting under pressure - showed up again for a period in the second half. They rattled Tyrone with five straight points as Sherlock and Quinn suddenly came to life.

Conal Keaney also contributed two points here to reinforce the fine impression he has made since abandoning hurling to concentrate purely on football this season. And though he had a tough day on Saturday, O'Shaughnessy is another huge plus for Dublin this year.

In fairness to the full-back line they were put under huge pressure by the weakness of their half backs. Cavanagh was running at the heart of a paper-thin defence all afternoon and always had an option to transfer possession either side of him.

At least Bryan Cullen can be switched back to his preferred role of centre back next year.

If Saturday is the last time we see Dessie Farrell in a Dublin shirt at least an immense career ended suitably with that late goal.

Now, for the first time since the Dublin-Meath saga of 1991 we have two teams meeting for the third time in the championship. It is just as difficult to separate the latest local rivalry that has enthralled the country.
