Dublin returned to training last night with lessons to be learned from their defeat to Galway at Pearse Stadium on Sunday.
Manager Pat Gilroy turned his attention to an analysis of the performance in the wake of the 3-12 to 0-13 defeat.
He and his backroom team have almost three weeks to correct the flaws in the team's display before playing Donegal away in their third Allianz NFL Division 1 outing.
Gilroy's first question will be: Why did his players relax the intensity of their approach after a positive start to the game?
He said: "I was quite happy with our performance in the first 20 minutes. However, we dropped our intensity in the last 15 minutes of the first half and that allowed Galway to take a stranglehold on the match."
The Dublin manager admitted that the opposition gave his men some lessons, particularly in the art of capitalising on scoring chances. However there were positive points on which to build for the remainder of the league campaign. "I was encouraged by our resolve in the second half and we put together some fine spells of football.
"We will obviously be collectively analysing the match in more detail over the next few days and will be immediately focusing on the Donegal match in three weeks."
The three main injury concerns arising from the game centre on midfielder Paul Flynn and forwards Conal Keaney and Bernard Brogan.
Flynn was concussed in the first half and was taken off. Conal Keaney was replaced under the blood sub rule midway through the second half and needed three stitches in his forehead. Bernard Brogan strained a hamstring and is receiving treatment.
