Tomás Ó Sé Picks All-Ireland Quarter-Finalist Most Likely To Cause An Upset

The lineup for this weekend's All-Ireland football quarter-finals is among the most open in recent memory.

Armagh sit as most punters' favourites to retain Sam Maguire, but all of the eight teams will harbour ambitions that the cup could be coming home with them instead on the final weekend of July.

Even the Orchard County have lost twice this championship summer, and the likes of Dublin and Kerry have faltered along the way to the last eight.

The fixtures have fallen beautifully, setting up four ties across the weekend that are extremely hard to call.

Of those four fixtures, Tomás Ó Sé thinks Monaghan v Donegal on Saturday afternoon is best set up to produce an upset.

Appearing on RTÉ's GAA podcast this weekend, Tomás Ó Sé highlighted three aspects of Monaghan's game that will have them believing they can upset Donegal in GAA HQ on Saturday.

Having topped their group, the Farney Army have enjoyed an extra week of rest compared to their Ulster counterparts, and Ó Sé thinks their half-lines and midfield could be pivotal in their push to reach the last four.

There's four obvious winners people will point to this weekend, and I would nudge towards Donegal.

But I do definitely think the way Monaghan are set up...the modern game...the middle eight is so vital. It's not always vital but Monaghan are playing extremely well and they're very adaptable.

I just feel that there's this thing in the north...I feel Monaghan don't really fear Donegal. Other teams would be affected by the fact that they're facing Donegal but I don't think it will impact Monaghan.

I'd give Monaghan a huge chance against Donegal. Even though I'd tip Donegal, I'd give Monaghan a huge chance.

They've a good bench coming on to the pitch, [Jack] McCarron is always introduced, he's held back. They have an impact there, as well.

I think it's a very, very tricky one for Donegal.

Much has been made of Donegal only having a six-day turnaround from beating Louth in their preliminary quarter-final last Sunday, and that could well be a factor against a hugely in-form Monaghan team.

It would be a huge result for Monaghan if they were to pull it off in Croker on Saturday but the way they are playing, it may not be out of the question.
