Chievo goalkeeper Stefano Sorrentino was the hero of the game.
“It was one-way traffic and we had so many chances. At times, we lacked something in terms of determination and that is what we need to improve," Di Francesco told Mediaset Premium.
“We mustn't fall into the trap of getting irritated by time-wasting, tactical fouls or the referee, because it doesn't make a difference.
“The statistics show we had opportunities in both the first and second half. We deserved a goal, but we didn't score and that is our responsibility. We must be more clinical and determined in front of the net.
“The crosses were coming in and we need to fill the penalty area better. We were centimetres away from finishing these chances off and created a great deal, so I am happy with everything except the goals.
“We can't just rely on Edin Dzeko's goals. It's true we aren't scoring as much as we did before, but Patrik Schick can play on the right or as a centre-forward, as we saw today."
