I think many people bet on AS Roma in that match. Even I personally am also included in it. To be honest, I didn't even suspect that AS Roma would lose in this match. The worst result I expect is a draw. I didn't watch this match in full. I only watched the second half. And I was surprised because it turned out that Roma had lost 2-1 in the first half. But I think that Roma will turn things around in the second half. Because Roma's ball control is also quite good. But it turns out I was wrong. And yeah this is really disappointing. Genoa apparently should not be underestimated. It seems that the 2 teams promoted from Serie B this season are quite high quality. And we should not underestimate it.
In fact, bettors have been ignoring bets on AS Roma for quite a long time, they are really hard to predict, sometimes they can be very good, but they can also get worse results and that was proven not only from last season but also at the start of this season where several of their matches showed how they still have to struggle to find the best performance they can show, maybe if you want to bet consistently choose their opponents because that seems more likely to happen, like the next match against Frosinone, a promoted team who have performed quite well so far, maybe Roma won't lose but a draw could happen and it would make things even more difficult for them.
