Juventus boss Maurizio Sarri admits they weren't at their best for victory over Hellas Verona.
Cristiano Ronaldo and Miralem Pjanic grabbed Juve's goals around a Danilo temporary equaliser, but there was a late scare when Federico Santander hit the bar, then forced a Gigi Buffon fingertip save.
“We watched it again afterwards and Bologna players were offside, so it wouldn't have counted anyway," Sarri told DAZN.
“I told the lads we mustn't try to control a game, sit on a lead or be comfortable, because otherwise we leave ourselves in these risky situations to the very end.
“The sensation is that we moved the ball quicker after the break and Bologna were getting there a fraction of a second later. I don't know if that's because we did better or they were tired, having worked so hard in the first half to contain us.
“There's a fine line between passing the ball effectively and just keeping ephemeral possession. In the last five minutes, we did it badly, as we lost the ball in banal fashion in our final third. We need to work on the details.
“It was a good game, but blighted by three or four horrible errors that we have to work on. I need to ensure the players realise we keep the ball for a reason, so possession is never kept just for the sake of it. We go into maintenance mode and that is never good."
