The Billingshurst-based attacker joined the Irish club on a season-long loan spell on Friday and had a dream start in their cup clash.
He netted twice in a 4-1 victory against Fermoy in the Munster Senior Cup.
The 20-year-old, who started his footballing career with Billingshurst’s youth teams and went to the village’s The Weald School, was praised by City boss John Caulfield for his second-half display.
He said: “We said at half-time we felt he was playing too deep, he needed to be in the box. He has pace and a good left peg.
“We needed more and in the second half, he did much better. He got a great header and then the free kick he whipped in at the end, I wasn’t sure if someone got a touch on it, maybe not.
“He has a brilliant left foot, but certainly we were saying at half-time, he was too deep. In the second half, he was much more lively and getting in behind them and causing trouble.
“There were a lot of new players coming in and these venues are tough to come to, we need to be on our game.”
