AC Milan boss Pippo Inzaghi admits they're suffering a confidence crisis after defeat to Atalanta.

German Denis struck the winner midway through the first-half.

Inzaghi lamented: "We just have to roll our sleeves up and work. There's nothing else we can do at this moment. We have the determination, but that's not enough anymore and we need to wake up.

"We take our share of the responsibility, but the only medicine for these issues is work.

"Our style of football that we had early in the season isn't coming out on to the field anymore and the team is feeling the tension."
