Roma team has performed very badly in the last three matches.
Yes, Roma performed quite badly toward the end of the season. There is a decrease of the performance of Roma player. I am not sure if it is caused by they failed in Europa league. But this shouldn't happen, AS Roma must focus on the remaining matches. Even in today match, Roma only can win with a single goal only. Roma lost the accuracy in scoring goals.
Those performances of Roma doesn't help De Rossi to get a long contract at Roma. It seemed Roma failed to perform their best when they were under pressure. The high target of finishing top four may be a factor of this bad form. This result will put De Rossi under evaluation of his worth to continue his role at Roma next season.
There is suggestion that Roma has given up early due to their small chance to achieve their target. The consistency of their competitors like Atalanta and Bologna made it hard for them. The failure in Europa League shouldn't a reason for this decreasing form as they were lost to a better team whose have a great season. The desperation of unable to get the target is the only explanation.
