Tomás Ó Sé doesn't think anyone will get close to five-in-a-row chasing Dublin this summer.
Speaking after the 18-point hammering of Roscommon at Croke Park, Jim Gavin insisted his players had been tested.
However, the five-time Kerry All-Ireland winner isn't buying it.
"I'm laughing at Jim Gavin describing that as a test," Ó Sé said on The Sunday Game.
"Roscommon's first game at home was vital. They came to Dublin and the pressure was on from the word go.
"It was as good a performance as I've seen from Dublin. If anything, from what we've seen, they're actually a level above last year.
"This is the best I've seen them in a long long time. Andy Moran said a couple of years ago you had to add on 20/21 points to beat them and they're averaging 29 points a game so far this season.
"It's phenomenal. Everything is there, the movement, the workrate.
"They really have the perfect storm in terms of their backroom team, management, players, attitude. There is no dip in form."

Ó Sé highlighted two aspects of Saturday's game that he believes shows that the killer instinct is as sharp as ever among both management and players.
"Jim Gavin doesn't do emotion. Bernard Brogan was sitting on the bench, he didn't come on. Cormac Costello must feel hard done by. He didn't come on.
"Con O'Callaghan, (Ciaran) Kilkenny, (Paul) Mannion, they're all ramping it up.
"Halfway through that second half, when the game was well and truly over, Stephen Cluxton beckoned (forwards coach) Jason Sherlock because some of the subs coming on were over-extending, forcing shots.
"Just to tell them and warn them 'We're sticking to the same plan'.
"There's just a hard edge about them. I don't see anybody tackling them this year to be honest."
