Is it possible for them to even improve on what they have shown in the first match? Obviously. But I think their performance is only going to get better as the season goes on.
Juventus' performance in the first half was very good where they were able to score 3 goals at home to their opponents. Meanwhile, Juventus slightly lowered the tempo of the game in the second half so that Udinese took several opportunities to build their attack. In the second half Udinese performed well and were able to take several shots at goal, but they did not score any goals so they finally had to admit defeat to Juventus.
Juventus are good at building attacks as well as defending, Massimiliano Allegri is satisfied with the result. Juventus need to be more consistent because they will only focus on Serie A. Massimiliano Allegri must put the emphasis on his players to win as many matches as they can, at least the Serie A title is their main goal this season.
