Dublin's Under-21 co-captain Cillian O'Shea admits the team "have trust in every decision management make", after their calculated dismantling of a hotly-fancied Donegal team in the Eirgrid All-Ireland Under-21 semi-final two Saturdays back.
"There's serious trust there," the Kilmacud Crokes player stressed ahead of Saturday's final clash with Galway in Tullamore. "And everyone knows their role, all the players know what their role is.
"We have huge respect for them, the work they do is serious."
Con O'Callaghan was gone for a black card after six minutes that afternoon while Andy Foley joined him before half-time with a recurrence of a hamstring injury.
Their most dangerous forward in O'Callaghan's absence, Colm Basquel, showed repeated signs of the rust he had accrued whilst injured while Shane Clayton onlu played in injury-time.
"I didn't know what happened," O'Shea revealed of the black card that forced O'Callaghan off.
"I asked around and they weren't really sure. Then just saw the black and it was like, 'Christ'.
"But even in the next play it went well, we went up the pitch and I'm not sure if we got a score or put it wide but it was just back to normal, do the job, the game plan that we'd planned for.
"There was no nerves or confidence problems."
Meanwhile, Dublin hurling defender Eoghan O'Donnell says "no final decision has been made" on whether Mark Schutte will line out for Ger Cunningham's team this summer.
Neither Mark nor his brother Paul have been part of Dublin's Championship preparations since a disappointing conclusion to this year's League campaign and relegation to Division 1B for next year.
And though Paul will not be returning to the fold in 2017, O'Donnell said Mark and Cunningham would review the situation after the completion of his final college exams.
"Mark has obviously been a huge player for us over the past few years but obviously with Cuala, and his final exams, he hasn't had a second to study," O'Donnell outlined.
"So Mark's taking a step away for a couple of weeks and hopefully we'll see him back after that.
"A decision will have to be made between Ger and Mark then to see what the best thing is."
Elsewhere, Paddy Brophy is expected to rejoin the Kildare senior football squad in advance of their Leinster SFC campaign after deciding to leave AFL club West Coast Eagles after three years in Australia.
"It's disappointing it's over, but it's time," Brophy said in a statement released by the club.
"I am going home for personal reasons, including homesickness."
