Juve beat Bologna 2-0 at the Allianz Stadium on Sunday with goals from Arthur and Weston McKennie.
“We don't need a new striker," said Pirlo.
“We are monitoring the situation, but a new striker is not a priority."
Pirlo was also asked about Paulo Dybala.
“He is trying to improve, he has problems at his knee. We'll evaluate him day by day."
Juventus are now seven points behind table leaders Milan, but with one game in hand.
“We must only focus about ourselves, our path depends on what we do.
