RTÉ GAA analyst Tomás Ó Sé believes Kerry got things wrong on the pitch and on the sidelines as they were shocked by Cork in the Munster SFC semi-final.

A Mark Keane goal with virtually the last kick of the game saw the Rebels manage a first win over their neighbours in eight years.

It also sent one of the real favourites in this year's Sam Maguire race packing their bags.

For Ó Sé though, the Kingdom didn't approach the game in the correct manner.

"Conditions were tough," admitted the five-time All-Ireland winner. 

"When you see Stephen O'Brien being changed and Brian Ó Beaglaoich being brought in, and Kerry setting up as defensively as they did - I think they got it totally and utterly wrong.

"I thought it was shambolic from the word go. It was as poor a display as I've seen from Kerry since 2001 when they lost heavily to Meath.

"They played Monaghan, they played Donegal, and we were raving about how direct they were, about the shape they had, the more defensive they were...

"I think they set up with pure fear today."

Kerry trailed at half-time, but had moved two points clear with four minutes left. Cork battled back to force extra-time, only for the Kingdom to twice more move two points clear in extra-time.

They simply couldn't kill off a stubborn Rebel outfit, with Keane's winning effort arriving all of 10 seconds before the final whistle of referee Derek O'Mahoney.

And Ó Sé said that the Kerry team displayed mental fragility in the important stages of the game.

"Coming down today the one thing you'd hope (is) that no matter what else, the Kerry team would be in a mentally strong place to really go to war with Cork.

"That's a given (but) that wasn't there today.

"It's a question that's going to be thrown at management. The subs they brought on were all defensive.

"They brought on Killian Spillane - he went very well. At no stage would they change it up and go full on, and go manic pressing the way they have been up to now.

"I just though it was - on the sideline and on the field - it was shocking from Kerry."

Cork are one win away from a first Munster title in eight years

Cork now have a route to the All-Ireland final which avoids the Leinster and Ulster champions, but includes a Munster final against Tipperary and, if they can win that, a semi-final against Galway or Mayo.

Ó Sé praised them for their work-rate.

"From a Cork point of view, I've given them grief over the years, they did it manfully.

"They set up defensively because of the danger that Kerry had up front - that danger wasn't there today. They were so sloppy today, Kerry were.

"But Cork set up a certain way, and stuck to it. They outfought around the middle of the park. They won breaks around the middle of the park."

Ciarán Whelan added: "That middle sector was where Cork won the game.

"They were like a boxer that hung in there - it was a snatch and grab, and they got it."
