AC Milan striker Rafael Leao admitted frustration after their 0-0 draw with Bologna on Monday night.
It means Milan are only a point ahead of second-place Napoli.
“I think it was a bad draw, as we did everything to get three points and extend our lead at the top. Now we have to focus on the next match, start strong, defend well and win, which is what counts right now," Leao told Sky Italia.
“We just needed to put the ball in the net, that's what we were missing.
"We'll keep working, try to find what we've been lacking in the last few games and hope for the best."
