Rio Ferdinand has conceded that Jadon Sancho's inability to replicate his stunning Bundesliga form at Manchester United is "concerning" - just weeks after praising the winger's output.
United pursued Sancho extensively during Ole Gunnar Solskjaer's tenure and finally acquired the 22-year-old's services in a £73million deal last summer. But since moving to the Premier League, Sancho has been unable to recapture the form that saw him evolve into one of Europe's most coveted players.
Sancho was prolific during his time in Germany with Borussia Dortmund, where he notched 54 goals and 67 assists across four years. Compared to those figures, his returns since joining Manchester United (8G, 3A) have been disappointing.
