Juve currently lie second in Serie A, five points behind leaders Inter, who thrashed Bologna 3-1 at the Renato Dall'Ara on Saturday.
Speaking to Juventus' official website, Diego said: “In the first half we made little movement. There was too much distance between the midfield and the strikers and for this reason we struggled for a little while.
“In the second half we came out better and in the end we managed to win a very important encounter.
“Now, we must have the utmost concentration for the challenge with Bordeaux, a game that we can and have to win.”
