AC Milan head coach Marco Giampaolo believes that a lack of experience cost his side in their 2-0 Derby della Madonnina defeat to Inter.
The Rossoneri headed into the fixture at San Siro knowing a win would see them jump above their city rivals, however they were outplayed once again.
It took until the second half for the first goal to be scored after two had been ruled out by the Video Assistant Referee in the first half, and VAR had a part to play in the opener.
Marcelo Brozovic’s deflected shot had initially been ruled out for offside but was overturned, and Romelu Lukaku added the killer blow 13 minutes from time.
The result means the Nerazzurri move six points ahead of Milan, who have now lost two of their first four games.
Giampaolo revealed after the game that he was happy with bits of his side’s performance, but bemoaned a lack of discipline.
“We were too hesitant at the start, then as the game progressed, Inter showed their greater experience,” the tactician told DAZN, via Football Italia.
“The goal broke the deadlock and I was not happy to see that we reacted in an emotional way, so became less organised and less united.
“Milan were in the game throughout and only had that slight gap in terms of experience, which we had been able to bridge to a certain degree.
“Players were going into areas of the pitch they were not supposed to be in, so when losing the ball, we left gaps uncovered.
“I hadn’t minded the performance, as playing high we needed to run some risks and that is a choice we made. Sitting back and trying to play on the counter would’ve been a waste of energy.
“I liked the courage to keep pushing the ball forward and that lasted up until the opening goal, when we lost our shape. That showed a lack of maturity.”
Rafael Leao made the starting line-up for Milan and was one of the few bright spots.
“Leao is a good player, he is fast, agile and has skill,” Giampaolo continued.
“I thought his pace could cause problems for the Inter defence. He must learn to stay in the game throughout.
“Diego Godin up against him, for example, is a difference in experience. The good thing is that Leao is not a timid player, by any means.”
