“The important thing was to win,” the 31-year-old told Sky Sport Italia.
“We were still lacking a home win and we are happy that it finally came today.”
The Brazilian then said how, despite claiming three points on Sunday, Udinese have to keep improving.
“We have to do even better, especially in understanding the situation,” added Felipe.
“In the second half we had to keep the ball more.”
Udinese’s victory puts them in 14th place in the Serie A table, while Frosinone are still only just outside of the relegation zone in 17th, one point ahead of 18th-placed Bologna.
