Hello, and you're very welcome to this special day in Croke Park as Donegal looks to get back into their first All-Ireland semi-final in a decade. They face a Louth team brimming with confidence following their one-point victory over Cork last week in Monaghan.

Donegal have had an extra week of preparation and they hope that will have a massive factor in this afternoon's game. 

These two sides last met in the league back in March in Ballyshannon with Donegal coming out the victors that day with a five-point win. And while Donegal will come into this match as favorites, their opponents today are the very team that knocked Cork out of the championship, the only team that Donegal has lost to in either league or championship so far this year.

Donegal makes one change to today's starting team with Conor O'Donnell coming in for Mark Curran.

The teams today are as follows: 

Donegal: Shaun Patton; Conor O'Donnell, Brendan McCole, Eoghan Bán Gallagher; Ryan McHugh, Caolan McGonagle, Peadar Mogan; Ciarán Moore, Michael Langan; Shane O’Donnell, Ciaran Thompson, Daire Ó Baoill; Patrick McBrearty, Oisin Gallen, Niall O’Donnell. 

Louth: Niall McDonnell; Donal McKenny, Dermot Campbell, Dan Corcoran; Conall McKeever, Anthony Williams, Craig Lennon; Tommy Durnin, Bevan Duffy; Ciarán Murphy, Ciarán Keenan, Conor Grimes; Ryan Burns, Sam Mulroy, Leonard Grey.
