Former Kerry footballer Pat Spillane says there is a crisis among the county's footballers, who are paying the price for failing to develop younger players in recent years.
The Kingdom have lost their first two National League games - to Mayo and Dublin - and Spillane feels that the blending of old and new players is not working.
Speaking to RTÉ Sport, Spillane explained: “Two matches, two defeats and the statistics make grim reading, with a paltry scoring return.
"Yes, Kerry are a team in transition, but the older lads have lost that yard or two of pace and the younger guys are just not good enough. The county are now paying the price for not bringing through adequate minor and U-21 sides over the last 20 years.
"Against Dublin our kick passing was poor, but more worrying was the lack of intensity, pace and passion. You can criticise players for many things, but when they don’t have heart, and many on the Kerry team did not show heart against the Dubs, then it is time to worry.”
The pundit added: “It is a crisis with a capital C.
"Three tough away games against Kildare, Donegal and Tyrone await and with Division 1 being very competitive this year, Kerry are going to find it tough. The rebuilding should have started last year."
