The first leg of the Coppa Italia semifinal at San Siro ended 0-0, with Milan the home team.
“I think the derby was less spectacular compared to the other two, as there's a lot at stake, the two teams were anxious and looking at the 180 minutes," Inzaghi told Mediaset.
“We'll think about it in the second leg, we want to reach the Final and win another trophy, knowing this was our 36th game of the season, we need to regain sharpness, but we are working on it."
Inzaghi continued: “I realise it hits the headlines when we don't score for four games, but we are working on it, we have talented strikers who are getting back to full fitness. There is inevitably a physiological dip, as we pushed with such intensity in November, December and January.
“We lost the Serie A derby, but had dominated for 75 minutes. We weren't as sharp this evening, but there was a Final up for grabs and both teams want to reach it, so approached it more tactically.
“Games are made of incidents. It was a bit of a tactical stalemate because so much was at stake. We are trying to recover physical and above all mental energy. We wanted to reach the Champions League Round of 16 and the Coppa Italia semi-finals with all our strength, so now we have to bear the brunt of those commitments.
“I think it might be a record for a side on March 1 to have a game in hand and still played 36 competitive matches."
