Man United will take on Atletico in a few minutes more in Oslo but Eriksen starts on the bench, with Scott McTominay, Fred and Bruno Fernandes starting in the midfield.
The midfielder started and scored a free-kick against Wrexham on Wednesday at Carrington.
Erik ten Hag isn’t sure if both summer signings Lisandro Martinez and Christian Eriksen will feature today against the La Liga side.
“We will see,” said Erik ten Hag when asked if both new signings would play today. “We want as many players as possible to get 90 minutes. They are not ready for that. We go step by step and give them playing time today or tomorrow or today and tomorrow.”
