Keith Long hopes that his Bohemians side can get a bounce from last week's FAI Cup win over Galway United to give their league campaign a boost.
Before the 2-0 Cup win over Galway, the Gypsies had gone seven games without scoring so the boss is keen to see confidence from that carried into tomorrow's Dublin derby at home to St Patrick's Athletic.
"The most pleasing aspect was the manner of our performance, particularly our passing game in the second half, which bounces us on now into tomorrow's game," said Long.
"We didn't lay a glove on St Pat's when we lost to them earlier in the season so we want to make amends for that and bring the game to them this time.
"We played very well against Galway. The most important thing was to get through to the next round but it was a very good team performance and we fully deserved to win."
Shamrock Rovers are also in action tomorrow, at home to a Finn Harps side whose morale has been hit by two heavy league defeats and an FAI Cup exit at the hands of non-league opposition, but manager Pat Fenlon is wary.
"They'll come here and make it hard for us," he said of the Donegal side.
"We have to improve our position in the league and we have a chance to do that on Sunday, Harps got a few tough beatings the last few games so they'll be out to make it hard for us.
"We went up there early in the season and they made it hard for us to get the win, bit of a scrappy win, so I'm expecting nothing different," added Fenlon.
