Inter Milan boss Luciano Spalletti was upset with his players for their 1-1 draw with Chievo.
Sergio Pellissier struck with a lob in stoppages to cancel out the Ivan Perisic opener.
“It was not dissimilar to our other recent games against Chievo," Spalletti told Sky Sport Italia.
“They know how to use this very direct style of football with the long ball and we allowed ourselves to be surprised. Clearly, we have to work better on these situations, as we had so many chances to kill off the game and didn't take them.
“Right at the end, this hole in the defence opened up and Pellissier took full advantage."
