Donegal manager Declan Bonner sees defending champions Gaoth Dobhair and 2017 winners Kilcar as the joint-favourites for this year's county football title.
On Saturday RTÉ Television will be showing live coverage of two of the four quarter-finals, with the four strongest looking teams left in the draw all kept apart.
On RTÉ will be Milford against St Eunan’s with a 5pm throw-in followed by Kilcar taking on Killybegs at 6.45pm.
On Sunday, Ulster champions Gaoth Dobhair put their title on the line again against Bundoran with Naomh Chonaill versus Glenfin the last of the quarter-finals.
"Gaoth Dobhair topped their group, they’re not playing as well as they were 12 months ago, but they’re starting to pick up a bit of momentum and they ran up a big score against Ardara last weekend," said Bonner, speaking on the latest edition of the RTÉ GAA Podcast.
"They have a really strong squad of players, had a really good run through Ulster last year and they’ll definitely fancy their chances of making the last four.
"The other game on Saturday is Killibegs aginast Kilcar. Kilcar are joint-favourites along with Gweedore to win the championship.
"They’re very strong and last season they were missing Patrick McBrearty after he picked up that injury in the Ulster final and he missed the club season last year. Ryan McHugh was out injured and they were beaten last year.
"They are very strong and they came through the group well. Killybegs would be missing Eoghan Bán Gallagher, but Rory Gallagher and John Cunningham are looking after them. That’s a local derby. It’s very difficult to see past Kilcar.
"At the start of the season you’d have been looking at St Eunan’s, Naomh Chonaill, Kilcar and Gweedore to be in the last four and that’s what it’s looking like at the moment, but the other four sides involved will be sure to want to have their say."
Gaoth Dobhair were one of the stories of the GAA year in 2018, the small club from the Donegal Gaeltacht winning a county title and going all the way to the All-Ireland semi-final, where they were beaten by eventual champions Corofin.
Kilcar won the Donegal crown after a 24 year wait 12 months previously and their defence last season was knocked by injury.
Donegal made it to the Super 8s All-Ireland quarter-final stage this summer, but for the second season in a row under Bonner they failed to make it as far as the semi-finals.
He hailed five in a row champions Dublin as the greatest football team of all-time, though added that it's up to everyone else to meet the standards they’re setting.
"Other counties can talk about a lack of funding or whatever, but we have to get our own house in order, no more than Mayo, Kerry, Tyrone or any other county," he said.
"Going after the Dubs is no easy task, but we have to go about it and prepare as best as we can. I feel there is a number of teams that can really go after it and we feel in Donegal that we’re one of those."
RTÉ 2 Television's coverage of Milford v St Eunan's and Kilcar v Killybegs starts on Saturday at 4.45pm
