We'll meet again
An interesting rivalry has built up between Monaghan and Tyrone since 2011, with the latter 3-2 ahead in their championship encounters since then. A look at the results indicates the closeness of those matches and, if you believe most commentators, it's going to be tight again as the pair face off in the All-Ireland semi for the first time.
On 20 May last, Omagh was the venue for an Ulster quarter-final clash where the Farney deservedly got the the better of Mickey Harte's men on a 1-18 to 1-16 scoreline. Monaghan's strong running and support play put the home side on the back foot for long spells.
Some trademark points from Rory Beggan and Conor McManus were prominent in the highlights reel that followed as Monaghan laid down an early-season marker.
A fortnight later, however, they were rocked back on their heels when a Fermanagh goal at the death denied them a place in the Ulster final.
The road to redemption along the qualifier route was a relatively straightforward passage as Malachy O'Rourke's men easily dealt with Waterford, Leitrim and Fermanagh.
In the Super 8s, Monaghan held firm in tight circumstances late on to edge past Kildare. Against Kerry, they were the dominant force all through, but didn't close it out and David Clifford made them pay at the death in Clones.
It was still in their own hands when they headed to Salthill last Saturday. Looking like a side hell-bent on making amends for that slip against the Kingdom they dominated Galway, particularly in the second-half when their lead grew from two to eight points on the way to a double-scores win.
For the first time since 1988, Monaghan are in an All-Ireland semi-final. It's a target that this crop of players under O'Rourke's stewardship would have set for themselves - it's also a place where many pundits expected the Ulster side to be on the back of that provincial success that kick started their rise in 2013.
As for Tyrone, well we all know that they are masters at navigating the back door. Yet, their progress nearly came to a shuddering halt on a sweltering evening in Navan against Meath. They survived, just about. Carlow, Cavan and a feeble Cork side were then dispatched en route to the Super 8.
Harte's men ran riot against Roscommon before stretching the Dubs to the limit on the 'shortened' Omagh pitch. It was always going to come down to the game against Donegal in Ballybofey.
History was on the side of Donegal and indeed it looked like they would prevail with a quarter of the game to go. The strength of the Tyrone bench would prove decisive and between them Kieran McGeary, Lee Brennan, Harry Loughran and Declan McClure hit 2-05 going down the stretch to secure what was, in the end, an impressive victory.
That was then.. but what of now?
Have Tyrone improved from that Ulster quarter-final nearly three months ago? They probably have. The impact of their subs on Sunday last was pivotal - to finish with a stronger team from that which starts a game has been the recipe for much of Dublin's success since 2011.
Lee Brennan was the player who caught the eye when introduced in Ballybofey. He's not named on the side to start the semi. Don't be surprised if he does start, but Philip Jordan, in his column on these pages, feels Brennan will aid Tyrone's cause more as an impact sub if the game opens up a bit - "his fresh legs could open up the Monaghan defence," he adds.
Monaghan won the vast majority, practically all one would say, of Tyrone's kickouts back in May and a high percentage won again will go a long way to Monaghan reaching the 2 September decider. They must dominate the middle third. As a team Monaghan aren't as free-scoring as Tyrone, but if they get a stranglehold around the middle and kick 16 to 18 points then all involved can start dreaming about an All-Ireland decider.
Did you know
This will be the first all-Ulster semi-final since 2005 when Tyrone beat Armagh by a point.
Monaghan last reached the All-Ireland final in 1930.
Mickey Harte is in his 17th year as Tyrone boss. Malachy O'Rourke is leading the Farney for a sixth year.
Harte has led his county into a championship clash with Monaghan on eight previous occasions where Tyrone have won six and lost two.
Teams The Red Hand make one change from the last day as Rory Brennan comes into the starting 15 in the full-back line with Conor Meyler, who went off injured in Ballybofey, the player to miss out.
For Monaghan, Dessie Mone replaces Conor McCarthy in their only switch from Salthill.
Tyrone: Niall Morgan; Michael McKernan, Ronan McNamee, Rory Brennan; Tiernan McCann, Frank Burns, Peter Harte; Colm Cavanagh, Padraig Hampsey; Mattie Donnelly, Niall Sludden, Cathal McShane; Mark Bradley, Richard Donnelly, Connor McAliskey.
Monaghan: Rory Beggan; Kieran Duffy, Drew Wylie, Ryan Wylie; Colin Walshe, Vinny Corey, Karl O'Connell; Niall Kearns, Darren Hughes; Ryan McAnespie, Shane Carey, Dessie Mone; Dermot Malone, Fintan Kelly, Conor McManus.
Philip Jordan's verdict
"With two teams that know each other so well, at this stage of the season, there is bound to be some off-the-ball stuff going on. It’s an All-Ireland semi-final, I wouldn’t expect anything different.
"Ultimately Tyrone’s greater spread of scorers, and the fact that they seem to create more goal opportunities – their execution has left them down at times – should be enough to edge past Monaghan and seal a first All-Ireland final in a decade."
Tomás Ó Sé's verdict
"Incidentally, of the three teams left other than Dublin, I feel Monaghan are the team best equipped to tackle the Dubs.
"But Tyrone are still hanging around and I think Monaghan could do without meeting Tyrone, anybody else but Tyrone in fact.
"They’ve beaten them already this year but Tyrone are not the same team as when they met with Monaghan earlier on.
"I admire Mickey Harte, you have to give him credit for sticking to his guns with his system. If Tyrone can stay in the match for the first 50 [minutes] I will just hesitantly give it to Tyrone."
Humid and calm with a scattering of slow-moving showers. Overall cloudy but a few sunny spells will break through, with the best chance of these later in the evening. Rather warm in parts with highest temperatures of 18 to 21 or 22 degrees Celsius. For more, go to met.ie
