Dortmund manager has slammed the attitude of Adnan Januzaj after the forward’s season long loan was cut short.
Januzaj did not start any league game and has now returned to Old Trafford, with LVG welcoming him back after telling him not to leave on loan.
However, Tuchel believes Januzaj’s approach hurt his chances at success with Dortmund.
“It is a pity he did not show the desire and attitude you need to progress at his age,” the BVB boss said to Sportbild.
“My feeling was that he never was completely with us, that a part of him always stayed in Manchester and he compared everything here with United.
“We were not able to help him to shake that off.”
Van Gaal has told Januazaj that he must prove his fitness with United’s Under-21 side before earning a first-team recall.
