The Giallorossi played out a 0-0 draw at the Stadio Olimpico and eventually lost on penalties to the Serie B outfit.
“Above all in the first half we lacked more or less everything. Above all you can see some have lost confidence. It's not normal to not even try to take men on or take risks, only passing sideways or backwards," said Garcia.
“It is not normal that we fail to score a goal against Spezia after 120 minutes and go to penalties. Tactically we have played three games with clean sheets, but we have lost the balance and aren't scoring any more.
“It's not normal with the squad we had tonight and this is really a failure. We have to stay standing in the storm and need character, pride, other elements to prove we can do much better. This isn't good enough."
