Diego insists Juventus can still make the top four before the end of the season.
The Bianconeri currently lie sixth in Serie A, six points adrift of fourth place with just three games remaining this season.
"We have had highs and lows this season and now we must think about recovering," Diego explained. "We still have the possibility of qualifying for the Champions League and we don't want to lose sight of this objective."
The Brazilian then reflected on Sunday's stunning 3-0 victory over Bari.
"It was an excellent game in which the team showed itself to be concentrated.
"After the 0-0 in the first half, we came out more decisive and closed the game.
"This is an important result in our sprint to the end of the season and we are focusing on closing the year even higher up the table."
