Juventus coach Antonio Conte has spoken of his pride at seeing his team improve since the start of the Serie A season.
Unbeaten in 21 league matches, Juventus are second to AC Milan but have two games in hand - one of which is against Parma on Wednesday.
When the sides met on the opening day of the season in September, Juve were resounding 4-1 winners, and Conte feels both teams have matured since then.
"Both Parma and Juventus have changed a lot since the first match of the season - I remember that very well, we played an excellent match and opened the season well," Conte said on Tuesday.
"From that match a lot of things have changed, my team continued to grow in every way, tactically and physically, in the attitude and the organisation."
"We surely have grown, and I think Parma did the same."
The clash at Stadio Ennio Tardini was scheduled to be played on January 31, but was postponed because of snow.
Conte will be without Simone Pepe for the trip because of an ankle injury.
The 42-year-old coach said he was enjoying watching his team deal with the pressure of being title challengers.
Juventus were relegated to Serie B for the 2006/07 season after being involved in a match-fixing scandal, but secured promotion and are now on track for their first top-flight title since 2002/03.
"I think that what's happening to us this season is making us very happy, because years have passed since last time we lived a season as protagonists and competitive," Conte said.
"This is all a positive stress, that is positive, good stress, and not distress, that is negative stress."
"It's surely good for us because we're going through something great, something we should be very satisfied and proud of, because we're competitive again and it all happened in just a little time."
