Man Utd boss Jose Mourinho makes transfer demand to Ed Woodward over new addition

“Mourinho is obviously cautious about having a director of football brought in above his head, who would have the authority to sign players and who might recruit players he doesn’t want,” Castles told The Transfer Window podcast.

“He doesn’t want to be working with someone he doesn’t trust in that position.

“He’s not against the idea of a director of football in principle.

“In fact, he thinks it could be helpful to have an ally in the camp – or at least someone to take some of the heavy load away in terms of the search for players, in terms of recommending players to the board, in terms of arguing with the board that this particular signing, for example Koulibaly, is the right one at this particular moment.
