LONDON (Reuters) - Jadon Sancho's lack of game time at Manchester United is "hurting the soul" of the man who sanctioned his 73 million- pound ($100 million) move to Old Trafford, Borussia Dortmund CEO Hans-Joachim Watzke.

The 21-year-old England international has started only two of United's five Premier League games and was an unused substitute in the 1-0 defeat by Aston Villa on Saturday.
