Manchester United captain Wayne Rooney is still a world-class player, according to Liverpool manager Jurgen Klopp.
The England skipper has lost his place in the starting XI for club and country going into Monday's huge Premier League clash with Liverpool at Anfield on Monday.
"Wayne Rooney is a goalscorer and a threat," Klopp said at his pre-match media conference.
"A situation like this can happen in a long career. From my side he's a world-class player.
"But I am manager of Liverpool so I know it is not allowed to like United players!"
Klopp added: "Ibrahimovic was not there, Pogba - they are both world-class players and when they are in your team they are not worse than last year, for sure.
"Unfortunately this is a really strong side from Manchester, they know about football, they are experienced, cool in the right moments, they don't need world-class performances to win a game.
"Even on rainy days, it's possible to score and win - they have those types in the team, but it doesn't mean they will win the game. It just means they have a chance."
Klopp continued: "Very intense game, two good sides. They have big quality and we have to respect this, as we do.
"But this is Anfield. We have to show this. We have had a few nice atmospheres but I'm open for the best atmosphere.
"We need everybody in a Liverpool shirt in this game. Apart from the table, it's a very important game. I know about the history, I like the special stories. The whole world will watch this game, it's a big honour to be part of it.
"The whole world will watch Liverpool versus Manchester United. It's up to us to perform at our best!
"As long as I live Liverpool against United will never be just a normal game. You cannot and should not ignore the special circumstance of a game like this. You have to be ready."
