Inter Milan coach Luciano Spalletti was left angered after their 1-1 draw with SPAL.
“Clearly when you concede a goal like that in stoppages, it leaves a bitter taste in the mouth," Spalletti told Mediaset Premium.
“We certainly have a lot more work to do. I wouldn't say I'm worried. I haven't seen particular improvements even from when we had that winning streak, as we always had these blackouts where we lost the ball in banal fashion and didn't fight back.
“We can't find a balance of behaviour and homogenous mentality. Until we do that, we won't go far."
