Borussia Dortmund manager Lucien Favre has urged Jadon Sancho to stay with the club and continue to build on his superb recent development.
Sancho is a wanted man this summer, with Manchester united known to be desperate to sign the forward after Ole Gunnar Solskjaer made the 20-year-old his No.1 transfer target.
The two teams are thought to be some way apart in terms of agreeing a fee for the player, however, and it is looking more and more likely Sancho may be denied a dream move to Old Trafford.
Despite scoring a hugely impressive 17 goals and creating 16 assists in the Bundesliga this season, Favre insists Sancho can still get better, and has pinpointed the aspects the England international could still improve.
Favre said: “It is important that he stays with us. That is of course also important for the team. Sancho is of course a very good player but he must also have in mind that he still has a lot to learn
“He needs to have better control of the ball, to do more headed flick-ons and to improve his defending.
“He can’t just stop running and stand still for 10 minutes and then suddenly do something for the next 10 minutes. This applies to everyone else as well.”
