Luton Town boss Rob Edwards is under no illusions facing Liverpool on Sunday.
Edwards is a fan of the Reds' midfield.
They're brilliant, top players, they're almost going into a different team now from the one that was very, very successful," he said.
"They're evolving, but they're also winning.
"They're confident, they've got a very good way of playing, so it's a bit different from the team that won the league and won the Champions League.
"They've got one or two players now, Trent Alexander-Arnold, who has been a really important player for a long time, his role is evolving in that team.
"The new midfielders they've got in there can rotate around it, there's a freedom in that structure they've got.
"They're very well coached, top individuals, which makes for a difficult game."
