There's two Ulster SFC quarter-finals  down for decision and a last-four showdown in Connacht. RTÉ GAA analyst Tomás Ó Sé looks ahead to the action.

Cavan v Monaghan, Kingspan Breffni, Saturday, 7pm (Live commentary RTÉ Radio 1)

Let's say from the outset, anything could happen. I don't think league form is anything to be going on here. Malachy O'Rourke has stated this week, it's all about getting a performance. If Monaghan show up they have all the talent to perform and produce a win. The players they have, the Karl O'Connells, the O'Hanlons, the McCarrons, the McAnespies - plenty of talent.

Cavan had a tough league campaign but if the Championship to date has shown us anything it's that the league form or standing doesn't count for much at all. Cavan have only won one match this season under Mickey Graham but they weren't a million miles away in four or five of those matches. If Monaghan show up, Monaghan will win, but it's going to be a right tough battle.

Down v Armagh, Páirc Esler, Sunday, 4pm

Down were motoring brilliantly in the league and promotion from Division 3 looked to be guaranteed only for them to lose at home, Westmeath swooped in and took promotion. That must have knocked Down for six. But Armagh coming to Newtry will be saucy.

Paddy Tally's men will set up as Paddy Tally's teams do. They'll sit deep, they'll try to counter-attack, he's had huge success with this at St Mary's and Galway, and I can see the reasoning with it.

They beat Armagh two years ago but half of that team is gone. Kieran McGeeney brings a talented crop of players capable of playing really good open football, but without a win in the Championship in the last few seasons he is under pressure, there's no doubt about that.

Beating Fermanagh in the league was huge for Armagh because Fermanagh were that kind of defensive team that they always struggle to beat, and they beat them. They'll take confidence from that.

This won't be a classic. Armagh need to win and find a knack of closing out games; I think they will win this weekend.

Sligo v Galway, Markievicz Park, Sunday, 3.30pm

Still no Paul Conroy, Eamonn Brannigan or Damien Comer for Galway. London put up a great show against Galway and Kevin Walsh has made five changes, which is a lot.

The most interesting one I think is Bernard Power coming in for Ruairi Lavelle. Power was outstanding for Corofin in the All-Ireland club final - his kick-outs are brilliant.

Galway have bolstered their squad. I feel, with no disrespect to Sligo, I think this will be an inevitable win for Galway. They'll have to play better than they did in London, that's for sure. They want another cut off Mayo, they want to keep their foot on Mayo's throat.

They need to get the balance right. I think Galway are actually on the right track. The potential they have is serious. I expect Galway to get to the Connacht final.
