Meanwhile, it's set to be a busy month for the Blades in the transfer window, as they look to secure some quality new signings before the start of the new season next month.
One player who has left Bramall Lane is John Lundstram who was snapped up by Rangers after his contract with United expire.
Discussing the move, the 27-year-old's new manager Steven Gerrard said: “John is a player I have known for some time and knew he would enhance our squad.
“Having played in the Premiership, he has the undoubted quality to enhance our midfield with his technical ability and physicality and I was impressed with his attitude and ambition when we spoke over recent weeks. John is a winner and knows what is required to succeed at a club of this stature.
“He will add steel and presence to our midfield along with his quality which makes our squad much stronger, and to procure a player of John’s profile and experience is very pleasing.
“Myself and the staff are looking forward to working with John. We know he is also very excited to get started at Rangers. I believe they (the new signings) have quality and I will give them trust.”
