Manchester United boss Jose Mourinho admits Luke Shaw could face Watford this weekend.
Shaw suffered concussion after an aerial collision with Dani Carvajal during England's meeting with Spain last Saturday.
"I don't know [if he will play] - we still have a training session," said Mourinho.
“Contrary to some news, to some opinions, by the protocol point of view and according to our doctor, he will be free to play.
“The only situation we have to analyse is if you are going to play him when, during the week, he was not training with the team or if, even, he decides to play."
