Yes, I agree with you, it is still too early to judge a team. indeed there are several teams including AS Roma who have brought in a number of classy players so that it is very influential for the team significantly.
that's a challenge for a team that does have good quality. Even if Roma has a good game and squad, it's not necessarily that they can play consistently when facing a team with better strength.
Roma has a chance this season. but all must be supported by the application of strategies from the coach to conquer each opponent. many strong teams forget that tactics are very important to beat the opponent.
