Pioli said: We leave this tournament with regrets. Roma put in more quality and more determination over the two legs, so they deserved to go through.
We certainly lacked quality, as aside from perhaps not creating very clear-cut opportunities, we did have situations in the box that we should've made more of. We should've made more of the fact they were down to 10 men, but we didn't have the quality or determination to overturn a result like that after going 2-0 down."
He added: We didn't have the right intensity, we should've moved the ball around much quicker, not try to rush things, but we weren't precise in the final ball and didn't have the quality to finish the chances we did create.
"After defeats like this, it cannot just be about individuals not performing up to their standards, there's more to it. Roma played well, but we could've emerged from these two ties with a better result and we didn't do that because we did not raise our level.
Roma are well set out, we were inefficient in the two phases. When you concede this many goals in so few chances, and have 40 odd shots on goal and score only with Gabbia on a corner, that too means our quality was not up to par."
