My own personal opinion is that Levy is playing hard ball with Utd because Utd are refusing to sell Martial to us - either there is some movement from Utd or neither transfers happen.
Pretty sure that suits United though. Alderweireld will leave for 25m next summer but there’s no such obligation on Martial.
As I’ve said before Alderweireld is priced specifically for United. There is no other club that will pay +50m for a 29 year old defender that will cost 25m next summer. Not in the EPL and not in the continent. If United don’t bite no one will.
