Milan coach Sinisa Mihajlovic was bitterly disappointed after last night's heavy 4-0 defeat against Napoli.
The Rossoneri have lost four of their first seven games in the Serie A as they keep their position in the middle of the table.
"There's little to say," Mihajlovic told reporters.
"It's not nice to admit it, but Napoli were better than us. Credit to them, even if the first half was balanced. The match was over after their second goal and we showed ourselves to be weak mentally.
"It's what also happened in the previous match. I think we're subject to too many highs and lows. We have to find a solution and only by working hard and talking together can we find a way out of this situation.
"We have been working hard, but it's not enough. Today, I played the best side I had available to me. We were unable to react after their second goal and mentally we are a bit weak.
"Objectives? As I've said before, when you're at Milan you're objective is to always battle for the top spots and it doesn't change after 7 rounds.
"It's hard to imagine at the moment based on our performances and the highs and lows, but our objective remains the same and we will try and achieve that.
"The players we have brought in during the transfer window are important, some have come from foreign leagues and some are still young. They need time."
