Manchester United have not had a good enough offer for any player they are ready to sell, boss Jose Mourinho says, reports BBC Sport.

Mourinho will let unhappy players go but said United had "not received one single offer they are going to accept".

The United boss said goalkeeper Sam Johnstone would be allowed to leave on loan for the remainder of the season.

Aston Villa are understood to be among the clubs who are interested in the 23-year-old.

Mourinho said: "Sam is the only player I allow to go on loan because he hasn't played one single minute and for his development, he needs to play for six months."
