Antonio Di Natale gave the Zebrette the lead in the first half, but Diego Perotti equalised from the spot.
“We have not been good at keeping the lead, but we had incredible opportunities,” Colantuono told Radio Rai.
“It is a moment that we are finding particularly difficult, we have to stay compact if we are to hold onto points.”
Udinese lost striker Duvan Zapata to an injury, but are also missing both Guilherme and Alexander Merkel.
“When we recover our injured players, we will be able to play with much greater continuity,” he continued.
“We have lost important players like [Duvan] Zapata, we are counting on him,” Colantuono concluded.
Udinese still have yet to win at the Stadio Fruili this season, collecting seven points in as many games in Serie A.
