Sean Boylan has seen enough from Mayo in the last three games to suggest they can shock Dublin.
The former Meath manager was speaking at our Roadshow in Achill in association with SuperValu.
Dublin remain favourites to reach the All-Ireland final. But Mayo have bounced back from setbacks this season to get to the semi-final against the reigning champions.
"Of all the matches over the years, this is the one I give them more chance in," said Boylan.
"The resilience that they've shown to come back and improve and perfect their game like the way they've done in the last three games, it's quite extraordinary.
"Particularly for a team that had been around for a long time and have taken an awful lot of heartache.
"It's for all the world as though they're gladiators now and they're just relentless. Some of the forwards that they have found and brought in, how well they're playing. It's not just a one-man band anymore. They can get scores from anywhere now.
"And to me, the most important thing is that they're having a kick at it. Before this, they were always nearly obsessed in getting inside what they call the D. Now they're playing like Mayo can play. I think that will be very different for Dublin. They won't have experienced that. And Dublin are one of the most remarkable teams to have ever played. But I think Mayo - not because I'm [in Achill] - are six or seven points better than the team I saw playing the first part of the Championship. They are so ready now and I've never seen them like this."
