Liverpool boss Jurgen Klopp says they can handle any Jose Mourinho tactical setup on Sunday.
The Reds take on Manchester United tomorrow and Klopp suggested his side would be ready to face any style of play Mourinho cooks up for them.
"Jose is maybe the most competitive manager in world football," he said.
"I don't think he cares a lot about what anybody says after the game. I don't have the exact idea of how Manchester United will play.
"They have improved a lot in the last few months. They are a results machine again, getting result after result. We can be a different animal too.
"Manchester United is a strong side, but we can defend outstandingly good. If they park the bus, we have to go with it.
"If they attack more, we have to use the space they give us. It's a game on the highest level, especially the concentration level."
