Davies didn't really cover himself in glory as he came on (albeit the game certainly picked up at that point), but I can see why people aren't sold on Klassen. He did link up with Rooney to set up Sandro's shot and hit Gueye who had a decent opportunity on goal, so he was involved in some of the buildup. I think the biggest problem is balance in the squad. Rooney is taking up the space that Klassen wants to occupy. It's not his fault per say, but Klassen doesn't look comfortable on the field with him.
