Despite the fact that Roma controlled the ball more, Lecce attacked more, and perhaps De Rossi was lucky that his team did not lose today. But in this case for Roma, a draw is a bad result, since they lost points, and Bologna managed to beat Salernitana, and now Roma is 5 points behind the top 4. For now, this seems possible to fix in the remaining 8 games, but I have doubts that for Roma this will be possible. By the way, Juventus lost to Lazio, and now it becomes quite possible for Bologna to bypass Juventus, which is currently in decline.
Apart from the draw against Lecce, at least Roma has made great progress after De Rossi became coach of this team because they have only lost once so far, but Roma did waste the opportunity to keep their chances of sticking with Bologna to reach a position in the top four.
Lecce played very well in this match, but they were not able to maximize every opportunity they had, because there were at least six shots on target that could not be converted into goals, likewise, Roma did not have more chances than Lecce even though De Rossi's squad had more controlled possession of the ball, but Lecce was better in attacking.
My prediction is that Roma will only compete in the European league next season because the remaining eight matches and half of them are tight matches for them, including facing Bologna, whose position they are currently targeting.
