Marcus Rashford could be unsettled if Manchester United push through a deal for Ajax winger Justin Kluivert.
The Daily Express says United have been linked with a move for the Ajax starlet - son of Dutch legend Patrick.
Kluivert claims he is yet to receive contact from United, and Mourinho claims he is happy with his attacking options at Old Trafford.
But any move for Kluivert could have serious repercussions for Rashford - and the forward would have to assess his future at the club.
Rashford started on the bench for Saturday's 2-0 victory over Huddersfield.
