Currently, Juventus open with loan option only without permanent contract and looks not excited for Manchester United want to sell Jadon Sancho, beside have Saudi Pro League teams interested for signing Jadon Sancho but he looks not accept offer for playing there and keep stay with European teams. Juventus have advantage and close chance to sign Jadon Sancho because the only one of European teams have official bid offer and Manchester United hasn't many option except get deal with Juventus although as loan option.
Sancho is still young to be playing in the Saudi league even though the league is far more relevant and important than it used to be and there are more european players there now but still european football is still the best for now. If Sancho really want to redeem himself he needs to stay in Europe and play in a good league, Juventus or Arsenal is a very good choice for him if he can perform more at any of this clubs then he would be seen as a top player he use to be.
Have interested from Premier League teams Arsenal and Newcastle United for signing Jadon Sancho but both teams not give official offer their interested for loan or permanent contract, but if Manchester United want to get above 80 million euro is very difficult because Sancho is not on the top level perform and have absent last several months with United.
Premier league is a good choice to prove United wrong that he was not the problem but the team, Newcastle are playing well and if Sancho joins he will blend in perfectly but can he outperform Gordon? I doubt it, but he has the qualities to do so.
80 million is a ridiculous price to sell Sancho judging from his performance recently he is not worth that amount and I doubt if any club can pay such high amount to sign him. Teams will bargain a lower price and i will advise united to sell him since he has decided to play elsewhere.
