The Wee county will be a big test. "I know we beat them in the Kehoe Cup, but they will be a different animal in the National League," judges Denis.
"They were missing a few guys when they played us, including a really good forward, Diarmuid Murphy. When he's around, he makes a big difference to them."
Fingal have to plan without Emmet McCabe, Gary de Loughrey and Dara De Búrca. Eoin Power had a leg injury, but he's expected to make it.
De Búrca was selected on the Nicky Rackard All-Star team last season after Fingal reached the semi-final.
"The management and squad sat down at the end of last season and we had a wish then to go into the National League," reveals Denis.
"It's good to play at National League level, and it will also be excellent preparation for the Rackard. There's a great interest in the squad and we are all set to get going now."
