After Dublin's second-half blitz of Mayo, Malachy O'Rourke marvelled at the collective pursuit of wanting to get better from Jim Gavin's side.
The former Monaghan manager, speaking on The Sunday Game, singled out three Dublin players in the ultimate demolition of the Green and Red to emphasise his point.
He said: "It seems to me that there is this never-ending quest for improvement from individuals and collectively.
"I was watching Paul Mannion. He scored a point with his right foot in the first half, and then scored points from both sides of the field in the second half.
"Two or three years ago he may have been more eratic with his shooting, he would not have been as consistent. He has now got to a really massively high level.
"Con O'Callaghan looks to have got a lot stronger and now can hold man markers off.
"I listened to Brian Fenton a couple of years who was saying that this is not the high point of my career.
"He was looking ahead to see how he could improve.
"Against Mayo, he showed once again how strong he was in the air and then getting forward and getting scores."
