Borussia Dortmund head coach Edin Terzic head coach praised a new loan signing.
While Sancho had disciplinary issues at United, the 23-year-old appears to be impressing Terzic in his short time back in Dortmund.
He told German outlet Sport: "It's true that Jadon arrived with good stats.
“Nevertheless, we know how the last few weeks and months have gone for him. If you see that with him, then we're happy about every training session.
“Both are outstandingly good. Nevertheless, we will handle it with caution."
