Neville told NBC Sports: "When you keep changing players and you keep changing your back three and you take five players off, you're basically saying to all of them, because they've obviously been taken off at the start of the game, that you don't trust them.
"Ten Hag kept doing that a few weeks ago when he kept changing the back players, changing the midfield. All of a sudden you've got a completely different system, a completely different set of players on the pitch at the end of the game. You can never get consistency.
"It looked really scruffy. They looked a mess at the end United with no real shape. In the first half they weren't brilliant but at least they had a shape to them.
"Pick an XI that you think are the best. Almost give that XI the faith and trust. Maresca's doing it now at Chelsea - he's playing an XI on a Sunday or a Saturday and then he's playing a different XI in midweek.
"He's sending some messages to the players that there's stability here and this is what we're going to do. When you change players all the time you're just spinning plates and there's no consistency. You need to build patterns together. You need to build that idea of what you are doing together."
