Massimiliano Allegri admits he was disappointed with Mario Balotelli's performance in AC Milan's 3-2 defeat to Parma on Sunday.
The mercurial striker struggled to make an impact as the home side focused their defensive efforts on frustrating his involvement, with a yellow card for diving the sum total of his efforts before he was withdrawn for Alessandro Matri shortly after half-time.
Allegri concedes he was concerned the former Manchester City man could have been sent off had his frustrations boiled over prior to his substitution, and was left aggrieved at his side's "naive" approach to the game.
"In the first half we created little and conceded twice on the counter-attack," he told Sky Sport Italia.
"We had to change something for the second half. I took off Balotelli because he didn't have a good game, while Poli had done well and it was a tactical issue.
"Balotelli had a few good moments, but overall it was not a good game. I needed a centre-forward who could really play that role and Balotelli wasn't doing it, although he has the characteristics.
"Balotelli had also been booked, so I was afraid we'd go down to 10 men.
"After the break we did more and went close to a third goal, but then that free kick happened at the end. We were naive and conceded two goals just before the end of each half.
"We should’ve closed down and not allowed any more space, but instead we got it wrong."
A last-gasp free kick from Marco Parolo compounded Milan to their third away defeat of the season and Allegri admits their form on their travels is a cause for concern.
"We are not balanced yet, as we go from great focus in the Champions League to distractions in Serie A," he continued.
"I said this game was fundamental for us to keep up with the top six, but as they all won this weekend it becomes even more difficult.
"We need to improve a great deal away from home, as we've only picked up two points this season on our travels."
There was some good news for Rossoneri faithful, however, as Allegri confirmed that Valencia defender Adil Rami and CSKA Moscow midfielder Keisuke Honda would complete their protracted moves to San Siro in the transfer window.
"Adil Rami and Keisuke Honda will be joining us in January and that will strengthen our squad," the 46-year-old added.
