West Brom have offered £13m for United's Schneiderlin and Jose Mourinho has confirmed he can leave.
Morgan Schneiderlin joined the Red Devils in 2015 for £25 million from Southampton
"My answer is simple: if he's playing regular with me I have the right to say 'no way'. If he's not playing regular I have no right to say to a player 'you are going nowhere'," Mourinho explained.
"My answer was if the offer is right, and our board thinks that the offer is a good offer in relation to the quality of a very good player like Morgan, I would not stop him going".
