You mean Roma lose the race against Bologna? The points difference between these two teams is just three points, a non sustainable gap which could change rapidly.
From what I see, Bologna don't have many hard games to play except from Roma itself, Napoli and Juventus. In the other side, Roma didn't lose any game after the signing of the new coach but they have harder games to play. Apart from these mentioned above, there is Atalanta and AC Milan that might be challenging..
Difference between Bologna and Roma is very small, only three points and it's too early to conclude Bologna will win and Roma will lose it. They have opposite strength, with Bologna it is their strong defense and with Roma it is their powerful attacking. Bologna with not too good attacking, can easily have issue to score goals and get three points. If they fail to score goal, it is nearly unable to win and get three points in their match and it will be chance for Roma.
Roma in contrast, have good attacking power but if their defense system can not cover Mile Svillar, scoring goals might not be enough to help Roma win and have three points in their match. This race between Bologna and Roma is very interesting but there are other clubs ready to join this race too like Atalanta, Napoli.
Inter's match against Napoli was beyond the expectations of the gamblers because I'm sure the hopes of the gamblers were that Inter managed to win against Napoli. However, if you look at the number of times Inter kicked the opponent, up to 19 times but failed to score another goal and this shows that Napoli has increased defense.
The shocked and disappointed defeat in Champions League round of 16 actually affected Inter Milan. They returned to Serie A, played against with Napoli with not best mental condition so that this draw is not so surprising result with me.
