Karius used several social media messages Sunday to apologise to his teammates and Liverpool fans.

In one he said: "Haven't really slept until now... the scenes are still running through my head again and again. I'm infinitely sorry to my teammates, for you fans, and for all the staff. I know that I messed it up with the two mistakes and let you all down."

In a second message Karius said: "As I said I'd just like to turn back the time but that's not possible. It's even worse as we all felt that we could have beaten Real Madrid and we were in the game for a long time."

Meanwhile an online petition, started in Britain, calling for Real Madrid player Sergio Ramos to be punished for "intentionally" injuring Liverpool star Mo Salah had received more than 150,000 signature by Sunday night.

Salah had to go to hospital after a tackle 30 minutes into the game, prompting many Liverpool fans to say the injury seemed intentional.
