Leicester name the same starting XI which beat Tottenham 4-1 last weekend at the King Power Stadium.
It is the first time they are unchanged since August.
There are just two changes to the matchday squad with Youri Tielemans and Boubakary Soumare added in place of Caglar Soyuncu and Luke Thomas.
There are two defensive changes for Manchester United from their last Premier League encounter at Leeds as Tyrell Malacia and Harry Maguire drop out and are replaced by Lisandro Martinez and Victor Lindelof. Luke Shaw moves to left back.
Further forward, Garnacho starts on the left wing in place of Jadon Sancho.
