Liverpool manager Juergen Klopp, asked if he would be taking a close interest in City’s game with fourth-placed Manchester United at the Etihad Stadium on Sunday, said: “Of course we are interested in it, but we have no influence on it.
“We have to win the games we play. Those we do not play in we have no hand in it. We don’t think about it or talk about it, we just try to win our games.”

“In the end it was open, we needed a bit of luck, but you cannot win as many games in a row as we have without a bit of luck, you can’t do this by only winning when you are flying,” Klopp said.
