Inter head coach Simone Inzaghi admitted his team is feeling the strain of a demanding season after their 3-0 defeat to AC Milan in the Coppa Italia semi-finals on Wednesday.

With the Serie A and Champions League titles still on the line, Inzaghi is worried after a second straight defeat following Sunday's 1-0 league loss to Bologna, but urged his players to overcome the setbacks.

"Of course [I'm worried]. We're not used to losing two in a row," Inzaghi told SportMediaset.

"We need to analyse both defeats the right way. We didn't deserve to lose in Bologna, and tonight we ran out of energy in the second half.

"We have to keep going. There's both physical and mental fatigue. We need to be stronger than all of that."

With the tie locked at 1-1 from the first leg, Luka Jovic scored twice for Milan and Tijjani Reijnders netted a late third to see Inter eliminated by their great rivals.

"This journey has brought us a lot of joy, but also some disappointments, like tonight," Inzaghi said.

"We should've done better. We lacked sharpness in both boxes at key moments of the game."

The Italian manager insisted that a packed schedule is no excuse, while his team must regain confidence for the final stretch of the season and ahead of hosting Roma on Sunday.

"We've had a more packed schedule than others, but again, it's not an excuse," Inzaghi said. "If we didn’t make it to the [Coppa] final, it means we didn't do enough.

"There’s one month left, and we have to keep going with confidence. Tonight, Milan deserved it, and it’s only right that they’re going to the final.

"We'll try to bounce back and give it our all on Sunday against Roma."

Milan's victory means they will play two finals in a single season, having beat Inter in the Supercoppa Italiana final, for the first time since 2007-08.

It also marks only the third time ever Milan have lost three derbies against Inter in a single season, after previously doing so in 1971-72 and 2004-05.
