I will tell you that I expected more from Roma in the match with Juventus, which lost a lot of main squard players due to injuries. But despite this, Juventus looked better and could even count on winning the match. Many said that the transfer of Dybala is an effort for Roma, in fact he cannot do anything on the field, maybe Juventus did right, that did not want to raise his salary. 
Now we still need Milan to lose points in the next matches and none of the leaders go into the gap, all for the sake of interige. 
Yes Juventus has close to seven injured players and almost all of them would not recover until September and October respectively. But Juventus is a big team with a lot of talented and experience players that can be able to at least get some good result until the team becomes complete. But in that match against Roma, Juventus was a better side. They even had one of their goals canceled due to VAR decisions. Now we still need Milan to lose points in the next matches and none of the leaders go into the gap, all for the sake of interige. It would be quite unfair to rate Dybala based on his performance against his former club, the season is just starting. Hence, he needs more time to justify the trust Roma has in him.
