Finally we get to the second semi-final this weekend. I don't know what it is about Tyrone and Kerry, but the blood flows quicker in me anytime that those fellas play.

Tyrone have got all their bodies back on the field for it and the extra week has worked miracles.

In my heart and on paper, I do think Kerry are a better team than Tyrone. However, I don't know what it is - is it the past or is it the fact that Kerry have not played in five weeks or is it that we haven't got a clue what's gone on in Tyrone - but something inside me has me stressed about this game.

If Kerry are not 100% focused tactically and more importantly mentally, then Tyrone have the armoury and the players to make this go to the wire.

There is a siege mentality with them when it comes to Kerry. They seem to harness on it and the word 'ambush' has been mentioned a lot and that's something that could be really, really pertinent this weekend.

I wonder about Kerry at times. They are firing on all cylinders this season. That comes from obviously Páirc Uí Chaoimh nine months ago when Cork stunned them completely.

They are playing with an anger this year and they are blowing teams away: Galway, Roscommon, Tyrone and then Clare and Cork in the championship.

Their main players and forwards like Paudie and David Clifford and Seanie O'Shea are flying it but their defenders have got that little bit tighter. But I don't know if they have been tested fully but going forward Gavin White, Tom O'Sullivan and Brian Ó Beaglaoich are outstanding.

Their kick-out press has blown teams out of the water. They have teams so much on the back foot that it is not hard to figure out that they have not been tested. Dublin are the only one with four goals in one half hour.

They put Kerry on the back foot with their pace and their directness but they got kick-outs away, that was the main thing. The reality is Kerry have no right to assume that they are better than what's left in this championship or that they are champions-in-waiting like everybody is touting.

They actually have to win an All-Ireland before teams will fear them and I've no doubt that Tyrone don't.

Tyrone have a point to prove as well because they haven't beaten a big team up in Croke Park since 2008 so there is a bit of pressure on them as well.

Seán O'Shea kicks a point despite the efforts of Niall Morgan during the Allianz League semi-final

Kerry did embarrass them in Killarney, put six goals past them and crushed Niall Morgan. I can't wait to see how both goalies fare because I think Shane Ryan hasn't been put under the same pressure that Morgan has this season. I think teams are so afraid of Kerry's forward-line that they back off Shane Ryan. I think that's a mistake.

Since Killarney, Tyrone have beaten Cavan, Donegal and Monaghan in the championship. They are Ulster champions. Along the way, the defence has improved. McKernan, Hampsey, McNamee won't be afraid of Kerry's main forwards.

Then they have Kieran McGeary, Conor Meyler and Frank Burns going back and being a threat going forward as well.

If Kerry, for whatever reason, don't show up, they could lose this game

If Tyrone are to win, they also have to focus on the forward line. They will have to hurt Kerry on the other side. With the extra two weeks, Darragh Canavan and Cathal McShane will be in better shape but it will be Darren McCurry and Mattie Donnelly that will be really firing - especially McCurry.

Conor McKenna loads the gun for the boys to fire. I think joint-managers Brian Dooher and Feargal Logan are different in that they understand that they need the two or three inside forwards.

So if Kerry, for whatever reason, don't show up, they could lose this game there is no doubt about that. But if they play the way they have been playing and if they are tuned in, I think Tyrone struggled against Monaghan in the second half because Monaghan pressed up on them and suffocated them. Kerry need to do the same thing. They need to land with that attitude that they have had all year.

I think Kerry will win. It's hard to predict by how much. It could be by a bit but I'm not sure it will.
