Inter Milan boss Luciano Spalletti says they need to toughen up mentally after their 1-1 draw with Chievo.

Sergio Pellissier struck with a lob in stoppages to cancel out the Ivan Perisic opener.

Spalletti said, “We still can't manage to be determined enough, but we've got quality and when we have the advantage in a match, we need to use it to bring home the result.

“It's not a physical issue of slowing down towards the end, it's purely a psychological one, knowing how to evaluate the various situations.

"Every now and then we make decisions that are counter to what we ought to."
