Saints' striker, Christy Fagan, is available for selection having missed the first three league games due to suspension.
Fagan admitted that while making his full league debut against his former club would be a surreal experience, it is one that he is relishing having missed out on the Saints' first three league games of the season after a red card from his time at Bohemians was carried over to the 2012 season.
“It's funny that my first game for Pats could be against my former side, but that's football for you.
“After starting the Setanta Cup games against Cliftonville this season, it was really frustrating to have to sit out the league games.
“It was great though to see the lads make a good start to the league season, but hopefully I can get in the team and play now.”
Fagan had mixed fortunes playing against the Saints last season, as he received a red card in a 1-1 draw in Richmond Park, while he missed a penalty in the 2011 Leinster Senior Cup Final.
The former Manchester United youth is hoping that his fortunes will be different in this fixture come Sunday evening.
“In the last game Chris Bennion made a great save from my penalty, but hopefully that'll change on Sunday.
“Any Dublin derby is always going to be a real challenge, but this is one I'm really up for.”
