Sinisa Mihajlovic says a lack of accurate passes cost AC Milan two points in Saturday's draw with Empoli.
AC Milan were ahead twice thanks to goals from Carlos Bacca and Giacomo Bonaventura but were unable to stop Empoli from equalising both times.
The draw kept Milan in sixth place in Serie A, and Mihajlovic was frustrated not to have taken an opportunity to move closer to European slots.
"We came here to win and we're disappointed not to have achieved that because when you take the lead twice like we did, you have to go on and win the match," Mihajlovic said.
"We should have done better on a couple of counter-attacks, but we were not clinical enough and we weren't accurate enough with our final passes."
Mihajlovic also said Milan should have been awarded a penalty that would have sealed the victory after Bonaventura had put them 2-1 up.
"I think the final result is a fair one, but we had a clear penalty which was not seen by the match officials and we would have killed off the encounter with the score at 3-1," he added.
"There is however no shame in drawing here at the Castellani. Empoli are one of the in-form teams at the moment. Apart from Juventus, a host of other sides have struggled at Empoli much more than us."
