It’s probably no exaggeration to say it’s now or never for this Dublin team, the chance to prove exactly what they’re made of. There can be no excuses in Croke Park this evening.

We know Dublin’s desire for All-Ireland success can’t be much greater than it is now, and their age profile is exactly right. So they need to start delivering, and by that I don’t just mean their work ethic and physical fitness, but mental fitness too, and if they really do have the quality to be considered contenders. If they beat Tyrone this evening I suspect they’ll have answered those questions in the process.

Manchester City have unveiled their new €40m man, Sergio Aguero, at the Aviva Stadium tonight.

However, City boss Roberto Mancini has said the player needs time to rest which means he won’t be playing in the Dublin Super Cup this weekend.

Mancini wouldn’t even confirm that Aguero will debut in tomorrow week’s Community Shield clash with Manchester United, saying only that he hoped he would be “available”.

Aguero said: “In five years I have only had one holiday so I’m used to it. One week of rest and a couple of days of training and I’ll be ready to play.”

CONAL KEANEY’S motorcycle accident yesterday morning has cast a cloud over Dublin’s attempts to reach an All-Ireland semi-final for the first time since 1948. Keaney sustained a fractured ankle and tore his cruciate knee ligament when hit by a van. As a result, Anthony Daly will not announce a team until tomorrow.

This is it for Dublin. The league success will lose its lustre if they cannot beat the Division Two champions. Many of their Leinster final excuses are valid. They were always going to struggle without Ryan O’Dwyer’s ball-winning ability at half forward while the rejigging of the defence after Tomás Brady’s knee injury failed to contain the Shefflin-Power-Larkin onslaught.

AN INVESTIGATION into fraudulent welfare claims led to the arrest of five people in north and west Dublin yesterday.

Eoghan O’Gara has won a surprise recall to the Dublin starting line-up for Sunday’s Leinster football semi-final against Kildare. O’Gara impressed off the bench against Laois in the last round but manager Pat Gilroy was not expected to tinker with his front line of Diarmuid Connolly, Bernard and Alan Brogan.

Instead, Kevin McMenamon was dropped from the attack when Gilroy named his team this morning with Alan Brogan moving out to the half forward line and O’Gara handed the number 14 jersey.

Dublin and Galway come face to face on Saturday evening in what will be only their third ever meeting in the Championship.

It will be the first time they have met since Galway came into the Leinster fray last year, and Dublin will be hoping the success they have had against the Tribesmen in the past will be replicated at O’Connor Park.

The Dubs got the better of the Tribesmen in the 1941 All-Ireland semi-final, and prior to that had come out on top in the 1924 decider.

Defenders Maurice O’Brien and Oisin Gough will start for Dublin in tomorrow’s Leinster SHC quarter-final against Offaly at Croke Park (throw-in 2pm).

First choice full-back Tomas Brady, who is nursing a knee injury, and centre-back Joey Boland (shoulder) have been ruled out for the Dubs’ Championship opener.

O’Brien and Gough come in as their indirect replacements, with Peter Kelly moving to full-back and team captain John McCaffrey switching across from right half-back to centre-back.

However, anyone who wishes to attend will have to pass through metal scanners, security checks and the president will speak from behind a plexiglass screen.
