When they last met...
When Manchester United and Liverpool met in December, Klopp's side were top of the table and United sixth.
Before the game we asked you to pick a combined XI, and midfielder Paul Pogba was the only United player who made it into the team.
Since losing that fixture at Anfield, United are unbeaten in the league, with eight wins and a draw under interim manager Solskjaer.
