Massimiliano Allegri said Juventus “never had a first-half like” their poor showing against Monza on Sunday.
The Bianconeri went in 2-0 down to the visitors at the break and were unable to turn it around in the second-half as Raffaele Palladino’s men completed a league double over them.
Goals from Patrick Ciurria and Dany Mota were enough for Monza to secure a 2-0 win at Allianz Stadium, following their 1-0 win against Juve earlier in the season in Palladino’s first game in charge.
Monza became only the second team ever to win both their first two games against Juventus in Serie A, after Inter in 1930.
Speaking to the media after the defeat, Allegri said: “I’m angry, we can’t concede goals like that. We’ve never had a first half like today.
“We have to think about working on the field… we need to examine our conscience and start playing with intent again.”
It was the latest setback for Juve after being hit with a 15-point deduction in Serie A related to previous transfer dealings, and Allegri was left in no doubt how much work there is to do to rescue their season.
“Reality says that we have 23 points, so we still have to win many more,” he said. “This is reality, and if we don’t look at it, we’ll get hurt.
“We are all responsible for the performance… In [our last] three games [in the league] we won just one point and conceded 10 goals.
“We facilitated the Monza goals, they came out with disarming ease. You can’t allow them to get into the defence like we did. They got through us too easily.
“We didn’t have any reactions… The last few performances were not up to par, when you lose you have to lose in another way, [though] there was a different attitude in the second half.”
