You are right about Roma usual pattern. It is good not to get too excited about their good start because being consistent is really matters for team that wants to win championship. You are completely right that winning title is long shot for them right now because they need to learn how to keep winning even when they are not playing their best. Developing that strong winning attitude and deep team takes time. It will be interesting to see if they can change their old habits this season.
Gasparini received a good team, Ranieri prepared them well, but they started this new season very modestly in attack. If they manage to score only one goal per match, it’s good that their defense holds their opponents and doesn’t allow them to score. This way he manages to get victories, but knowing Gasparini, I’m almost sure that he will work on developing the attack. One goal per match is too little, and while they are lucky now and can win this way, such luck won’t last, it’s impossible to keep a clean sheet for the whole season.
