Bologna has interesting record this season because i have seen there are several matches results from them who ended with 0-0 i think it's clearly they are the team with defensive style because seems Thiago Motta is the manager who like that type of game and as a mediocre team i think Bologna performance was quite stable because since last season they can managed their position at top 10
But Inter Milan is unstoppable now although they were slipped from Sassuolo few weeks ago i think it won't be affect to their game and today i assume Inzaghi will do some rotation and possibly Martinez will be starting the match from the bench and his position will be replaced by Sanchez and although Bologna is a tough team but i am confident Inter will be able to beat Bologna probably with narrow score but Inter has low odds currently @1.39
As you said, it seems that Inter Milan is unstoppable this season. Because currently in the first half Inter Milan is leading 2-1. But I think Bologna is also quite good in this match. But they are not good enough when compared to Inter Milan. And it looks like the second half will still end with a score of 2-1. But maybe there will be another goal in the second half.
Currently Inter Milan is ranked 1st in the standings. And if Inter Milan can finish this match with a win in their hands, Inter Milan will be even safer to be in 1st place in the standings. And the good performance shown by Inter Milan is not only in Serie A but also in the Champions League. I think Inter Milan will indeed be a strong candidate again, even in the Champions League.
