I did expected Chelsea to sign a winger because Sancho needs to be replaced, and what am hearing is that Christopher nkuku will be sold, if the right price came in, but am still a little bit skeptical of the quality of your Joao Pedro because I haven't seen him play, and secondly his numbers like goals and assist is not that too impressive for him to be tag as high quality player, but nevertheless if he's given the fair chance next season, he might prove all of us wrong and even give a better numbers like goals and assist than Sancho.
Chelsea need to get rid of some names soon because the club has collected a lot of players and it is not good for their finances at all. Sancho is not the same player as he was at Dortmund, he has struggled quite a bit this year, maybe he should be returned to Man Utd and replaced by someone else, namely Joao Pedro, because he can be placed as a winger. No need to worry about his quality, I think his statistics are quite good, 10 goals 6 assists in 27 games with Brighton shows that Joao Pedro has potential + he is still very young.
Sancho is not taking his football career seriously and doesn't want to improve his performance so that clubs can pick interest in him. He is after being paid heavily, and he forgot to understand that there's time for everything. United wasted a lot of money on paying Sancho and the rest for their inconsistent performance. This has always make United to put him on loan to other clubs every season. If Sancho is sent back to United, it will be a burden on the club.
