ARMAGH EXPECTATION

Back in Division 1 for the first time in nine years, there has been a sense of expectation about Armagh's chances of making a mark in Ulster this year, having not featured in a provincial decider since they won it in 2008.

The path to Saturday's semi-final looked straightforward on paper as they got past Antrim with something to spare but the four goals in the 4-15 to 0-14 victory suggested greater dominance than the balance of play may have outlined.

They face a stern test of their credentials against a Monaghan side very much used to operating at this juncture of the provincial championship in recent years, although they do have some injury concerns around talisman Conor McManus and Darren Hughes, who were withdrawn during their win over Fermanagh two weeks ago.

The last meeting between the sides came in their Allianz Football League Division 1 North opener in mid-May where Armagh came out on top by a four-point margin, having not been behind at any stage of the contest.

That will give them confidence but Tomás Ó Sé is tipping Monaghan to find a route to victory, citing the latter's experience, durability and attacking threats - provided McManus and Hughes are fit and available.

DONEGAL WITH THE EDGE?

Donegal almost didn't make it as Derry pushed them all the way in last Sunday's quarter-final. That was until Patrick McBrearty came up with a brilliantly-taken winning point in Ballybofey.

Which means we get a renewal of their rivalry with Tyrone who had more to spare in dethroning last year's Ulster champions Cavan by eight points last Saturday.

Feargal Logan and Brian Dooher also welcomed back Cathal McShane after a long absence in another boost for their hopes of trying to go a step closer to bridging a four-year provincial drought.

But Donegal have an array of potent forwards to choose from while captain Michael Murphy made a welcome return early in the second half against Derry after his injury against Down.

It will be a tense battle between sides with ambitions of making a dent later in the championship and Tyrone will especially be smarting from defeats to Donegal in the league in May, in the Ulster quarter-final last winter, the 2020 league game and the 2019 Ulster semi-final - almost all by close winning margins. Whichever way it goes on Sunday, the gap between the sides will likely be miniscule.
