According to a news source Newcastle are interested in a loan deal for Harry Maguire. But the source looks like The Sun so I don't think this rumour would be reliable at all.

Actually there was a more serious rumour linking Tottenham with Maguire on Transfermarkt website a few days ago. But the probability of a transfer is decreasing day by day.
Honestly it would be really great for Manchester United if they get rid of him as soon as possible. On loan or permanent deal they wouldn't have to pay his salary or most of it at least. Because he is really no use for Manchester United. He will stay as a rotation player and he won't be a credible player when ten Hag has no choice other than putting him in the lineup.
