Finally, McGuinness expressed disappointment in the lack of scorers throughout the Donegal team on the day.
They had 12 different scorers in the semi-final win over Meath, but only six against the Kingdom with Michael Murphy hitting 0-8. While Kerry had seven different scorers, they had a goal and a series of two-pointers.
"Michael is Michael and he will carry that attention [from opponents] and he's carried that attention all throughout his career.
"That's why it's so important to have your 10, 11 or 12 scorers. That's why it's so important to have that spread of scorers because any day like that can happen and pop up and it didn't happen for us today.
"But they've given it their absolute all from the beginning of the year. They're a very, very good group to work with. Very dedicated, very focused on what they want to do.
"Today's not a good day for us and it's not a good day in terms of what we wanted to achieve."
