What AS Roma experienced was very, very embarrassing, how could they lose against a team that had never won this season, and their first victory was in this match. The quick goal in the 17th minute that Cremonese created was key, because with that goal they could be more comfortable and try to delay the game so that it was very difficult for AS Roma to score a goal back. Even though they were able to equalize first, in the end a goal from the white point in the 83rd minute really made AS Roma lose.
Problems with Roma is their defense is not good like rock and their attacking system is bad and lack of capability to score many goals. They are a club with less scored goals in top six of Serie A. To be fair with their defense, they will not have a good position (fifth) so far if their defense did not play well.
However as I said, their defense is far from a bunker and with bad contribution from attacking system, if they let opponents score goal first, it will be most likely a defeat for them. Cremonese had two excellent finishes to score two goals and beat Roma but it will not enough for them to stay in Serie A.
Pogba's situation was a prime example that it is not always the smartest decision to postpone a surgery if it is not necessary. At times it can do more harm than good and here that seems to have been the case.
I agree as postponing necessary surgery will be harmful for player body and it will affect their ability to recover well and regain their best fitness back. However it is not the case of Pogba who got many problems with injuries and his body in Manchester United. He was not able to play too many matches for Manchester United in his last two seasons for them.
The injury in early days of Pogba in Turin is a continuation of his more vulnerable body with injury that already began in Manchester United.
