Gennaro Gattuso demanded his AC Milan side become more ruthless in front of goal following another frustrating point in Serie A, this time against Empoli.
Alessio Romagnoli's poor turnover in defence led to the concession of a late penalty that allowed promoted Empoli to snatch a 1-1 draw on Thursday evening.
Lucas Biglia had opened the scoring after just 10 minutes for the visitors with a deflected strike, but his foul in attempting to atone for Romagnoli's mistake means the Rossoneri have now squandered seven points from winning positions.
Milan head coach Gattuso refused to single out Romagnoli for criticism, instead expressing frustration with a collective lack of killer instinct.
"At the moment we cannot say we are a great team. A great team is more clinical and solid," he told Sky Sports Italia.
"We are talking about another unlucky outcome again. We have to improve our finishing, because we are struggling.
"I have nothing to say to Romagnoli. If I say something to him, then I have to say something to those who had several chances to score.
"Mistakes can happen, but we must grow and whittle down them down as much as possible."
Ex-Roma man Romagnoli was more remorseful as he apologised to the club's fans for his part in the failure to secure three points.
"I'm disappointed because I made a mistake and I take full responsibility for it," the 23-year-old said.
"Without my mistake it would have been a different game, but now we have to keep working without listening to anyone and staying united."
Milan's hopes of putting the match beyond Empoli's reach were hampered by first choice striker Gonzalo Higuain's absence with a muscle problem.
The striker will be monitored ahead of a possible return away to Sassuolo on Sunday, where Milan must win to halt their slide down the Serie A table.
