Juventus coach Max Allegri admits they were poor for Sunday's 1-1 draw with Salernitana.
Adrien Rabiot struck for Juve in the 91st minute to cancel out Niccolo Pierozzi's first-half opener.
Allegri said: It was a bad first half. We started reasonably well, then made a mistake in our decision making. We became disjointed and we didn't hold our positions.
To concede a goal from a dead ball, we knew that Salernitana were going to be dangerous there. We didn't threaten them at all from set pieces. We needed to be more precise, but we weren't.
We did enough not to concede, we could have threatened more from set pieces, then Lean's chance, he shot when he could have developed the sequence better.
We just needed the patience to play properly, not to shoot when you don't need to shout, but to pass instead. We had a good reaction, then the same thing happened as in Roma.
You can't lose a match like that, otherwise you risk never picking yourselves back up again. A draw, now three days to prepare for the final.
You don't need to be frantic, but you do need to be fast.
The first minutes were similar to our game against Roma. We didn't exploit certain situations because of our decision making. I've said it many times, Wednesday is so important for us. You need coolness, clarity and patience.
The team has to improve. Now let's recover, it's going to be a nice evening on Wednesday, then we'll think about getting the points for the Champions League."
