I think his move to Chelsea reduced his playing form because the Sancho I knew that played in borrusia dortmund was an entirely different person as he was so in check with his playing style and also help the team in terms of goal but for now I think his form has greatly reduced and that deal is a really good deal indeed and who knows maybe he might get more playing time over there in Italy because that's what really going to help a player back in form.
He's still quite young, only 25, so it's still very possible for him to return to his best form and reach the peak of his career, and perhaps Serie A will give him that opportunity. Although Roma may not be the strongest team in Serie A right now, I believe under Gian Piero Gasperini, AS Roma will become even better, because he is a coach who is known for developing the potential of his players. However, if Sancho fails to adapt for the second time, then this will be a nightmare for him, but I hope this will not happen, because I see that quite a lot of players who started in the English Premier League, some of them have succeeded in shining in Serie A.
