The Reds travel to Bramall Lane on Saturday in the 20:00 BST kick-off, looking for successive top-flight wins for the first time in 2023/24.
Paul Heckingbottom's side have taken just one point from eight games since coming up from the Championship last season and Ten Hag has a 100 per cent record in charge of Manchester United against newly promoted clubs.
Casemiro has been ruled out of the trip to South Yorkshire, with the Brazilian remaining in his home country for a little longer after picking up a knock on international duty.
But there is good news for Erik as he welcomes defenders Raphael Varane and Sergio Reguilon back after injury, while Sofyan Amrabat is also available, despite missing both of Morocco's games.
