The former QPR striker impressed during Reds’ 2-1 defeat at League One side Gillingham on Tuesday night in the Checkatrade Trophy.
Since joining Crawley from Woking in the summer, the 22-year-old has only made one start in League matches, plus three appearances from the bench.
Cioffi said: “When I came here our relationship started on the wrong foot as he was on international duty for The Republic of Ireland under-21s.
“He didn’t have the chance to shine and the team was doing well so I had other priorities.
“He has shown me that his standard of training has massively improved and is really high and for sure he is a player I can trust.”
“If he is able to keep up this standard of training, we can go forward together.”
