Sassuolo outclassed the Viola on their own turf with Gregoire Defrel scoring twice.
“It's a step backwards, but ultimately the situations make the difference. We basically did everything, as we made the mistakes in attack and defence," Pradè told Sky Sport Italia.
“I am angry, because we have to do more. We must do more. This team has talent, but talent is not enough. You need more determination, more grit, heart, to show hunger and fight for every ball.
“Instead, we conceded two goals on counter-attacks from our own corners, I saw players who didn't give their all. People keep talking about our players being so valuable on the transfer market, but they've got to prove it on the pitch, not in the newspapers. Show what you've got.
“With the situation as it is now, we've got to spit blood and be humble just to secure safety, then we'll see about the future."
