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.
Roma is strong guys, I told you so
Jose Mourinho knows the fact of him and although he does not have a complete team (as you say the attack is not the top) he manages to equalize with Juventus
I expect great things from Rome
