Speaking to Goal, Jaap Stam said: "For Harry Maguire, he needs to play. If he stays, and he probably wants to stay, he needs to pick his moments when he gets the opportunity. He needs to show that he is the better player.
"It's not going to be easy but every big team needs to have at least four quality centre-backs. There are going to be suspensions, there are going to be injuries, the manager wants to rotate and then you need to prove yourself.
"It's not an easy situation because there is a lot of attention on him, people are saying things that are not making it easy to perform. You can see that he is trying his hardest not to make mistakes and to show people that he is a good player.
"But you need to not think about football, it needs to become something automatic when you are out there and to show your quality. If you are thinking too much about what you need to do, then eventually you will make mistakes."
Maguire is back at Manchester United after playing a key role for England at the World Cup, reaching the quarter-finals of the tournament in Qatar.
However, Erik ten Hag is likely to stick with Raphael Varane and Lisandro Martinez at centre-back once both defender make their return to full fitness.
