The Bologna team is no longer considered weak this season. In the last few matches we have seen good performances from Bologna players. Bologna have won 7 of the last 8 matches. Defeated only against Inter Milan, narrowly 1-0. Bologna players have performed very well in every match.
The performances of Bologna's attacking players are somewhat erratic, but not weak. But Bologna's defense is very strong. Bologna's defense is stronger than Roma and Atalanta. Also, the players are in a very good rhythm now. So for the fourth place in the table I consider the Bologna team more favorite than Roma and Atalanta.
Maybe Bologna's current standings are proof that Bologna is indeed better than Roma and Atalanta this season. But the question is whether Bologna will be able to continue to maintain their current performance until the end of the season or not. Because currently Roma has shown drastic improvement and looks like it has the potential to overtake Bologna. But Bologna this season is really extraordinary, they even beat Inter Milan this season, namely in the Coppa Italia. And Roma also lost last December. Meanwhile, Atalanta has lost 2 meetings with Bologna this season. So there is no doubt that Bologna is very strong this season.
