The best outcome should be winning, but to draw isn't a too bad result. I am very sure that Roma expects to win 3 points, Juventus also thinks the same. Winning against a strong team should bring positive impacts for the next matches, the players to be more confident. However, it is true that Juventus seems stronger this season, that's why AS Roma is difficult to beat them. Even, Juventus more dominated the match, ideally they can get 3 points. But Tammy Abraham makes Juventus fail to get full points.
I think this draw is understandable because Juventus and Roma are strong teams and are on a relatively equal level.
In a match all teams definitely want to win, when they meet a team of relatively the same level, a draw is very fair for both teams. Juventus have tried to take the initiative to attack to secure full points, but Mourinho squad played very disciplined, especially in defense. Roma were lucky to take home a point from Juventus and make them avoid defeat.
Mourinho is well aware of his squad's weaknesses. His attack is not strong. If he had played an attacking strategy against Juventus with such a squad, Roma's defeat would have been more likely. And so Mourinho did not want to take any risk. He wanted to be happy by scoring 1 point. And for this reason, Roma has played completely defensively since the beginning of the match.
On the other hand, I don't find Juventus' squad stable yet. Juventus have plenty of talented players in their squad. Yet their performance fails to impress us. Let's see if they are able to stabilize themselves in the upcoming matches.
