It wasn't a great pass from Paletta, that's true. He should have kept it on the ground and to Gigio's right side. Instead, the ball was bouncing and straight towards the goal to Gigio's left side.
HOWEVER, any school boy (goalkeeper or not) would be able to take care of that pass easily and so would Gigio 999 times out of a 1000. Let's just call it how it is and be fair here. We all love Donnarumma, but when he makes a mistake, he makes a mistake. That's all there is to it. The goal was 99% Donnarumma's fault.
But it wasn't a problem. We should have scored more than 1 goal against a terrible Pescara team that's conceded 67 goals in 30 games. The second half performance (for about 35mins) was just unacceptable. Instead of coming out from the break fuming to go at Pescara, we were timid, slow, and showed very little quality.
