Atalanta seems to have had better results in the last few matches than Roma, but we can see that Atalanta is facing a relatively weak team so they can win three times in a row, but Roma failed to beat Atalanta in the first meeting this season so the match at Atalanta's home ground will be even more difficult for Roma to defeat its opponent.
However, if you look at the performance of Roma, currently coached by De Rossi, I think Roma will provide different resistance to Atalanta. The reason is, after De Rossi coached Roma, the performance of his players improved very rapidly. Apart from that, when Roma played against Atalanta in the previous meeting, as far as I remember, Roma was still under the guidance of Mourinho. And under Mourinho, Roma's performance was not good so it was natural that they were held to a draw by Atalanta. However, Roma's performance is now much better than at that time, so the possibility of Roma winning the match against Atalanta is also very big in this match.
In my opinion, the match is probably going to end in a draw. Because I can assume Atalanta is going to play very defensively in that match. Because if they get one point, it is going to be a good result for them. But Roma is definitely going to go for a win. Predicting this match is going to be very complicated. But I have to say the performance that the coach of Roma was able to produce earlier, it is not happening right now. They are not as consistent or performing as well as they were when the coach was just appointed. I think there is a high chance for Roma to not win the match. And if they for some reason, lose the match, which is definitely possible, they might not end up participating in the Europa League. De Rossi is good but probably he was not ready to be the coach of Roma.
