Former Dublin captain Coman Goggins sees Mayo as the side most likely to derail the Dubs' four-in-a-row bid.
The westerners came agonisingly close to toppling Jim Gavin's side in the 2013, 2016 and 2017 All-Ireland finals and Goggins reckons they can emerge as challengers again this summer:
"I know their league campaign wasn't overly spectacular, but I'm not sure how much focus is put into that league campaign given guys are in Dublin and everywhere else studying," he is quoted in The Irish Independent.
"So, I'd say with the full group together, guys back on the field, that they certainly have the mental strength maybe…
"They certainly believe in themselves that they're good enough to beat them. What it is that lets them down in the last few minutes, only they can put their finger on. But I certainly think they're probably the team that could get to Dublin if they get the opportunity.
"Do I think Dublin will be beaten? Your heart would say no and that it's great to see them… coming out of the league final, the only word you could use is phenomenal what they've achieved, because for so long I was part of teams where consistency was a huge issue for us."
