Jurgen Klopp admits Roberto Firmino's injury had a 'catastrophic' impact on Liverpool.
The Reds were held to a goalless draw by Manchester United .
Liverpool boss Klopp told Sky Sports : "It was a strange game. We started really well. All the injuries in the game obviously cost us rhythm. It happened to us with 'Bobby' and that was a catastrophe.
"United played with a completely new midfield and three up front. We lost our rhythm and couldn't get it back. It was a game without a lot of highlights - it was intense. On days when United are beatable you have to do it and we didn't do it. We have a point more and Wednesday is out next game."
