The 25-year old made an error in stoppage time that led to a goal for Borussia Dortmund in the pre-season International Champions Cup game on Sunday.
After the friendly, Karius slammed his critics on Instagram, writing: “To those who take joy in seeing other people fail or suffer, I feel for you.
“Whatever it is that is happening in your life to hold this much anger and hate, I pray that it passes and good things come to you.”
The German received the backing of former Spain goalkeeper Iker Casillas after being criticised – and his Reds team-mate Salah.
The Egyptian star sent out a tweet to motivate Karius while advising him not to bother with those who write him off.
“Stay strong Karius, it has happened to the best of players. Ignore those who [email protected],” Salah wrote.

When Mohamed Salah was injured during the Champions League final many Liverpool fans were worried about just how badly the Egyptian King had damaged his shoulder and whether indeed he would be fit enough to return by the start of the new season.
Reds manager Jurgen Klopp was worried as well. So worried that he stayed in contact with Salah all throughout the World Cup to monitor his fitness, he has revealed.
Watch Klopp’s full comments below and hear what he truly thinks about the state of Salah’s injury.
Egyptian fans turned up in numbers at Mohamed Salah’s house after his address was leaked on social media. However, instead of being scared, the Liverpool star embraced the supporters and signed autographs.
The Pharaohs arrived back from the World Cup where they suffered a group stage exit and with speculation that Salah could retire from international football, fans made their way to his mansion after his address was leaked on Facebook.
His street was crowded by people and cars as they stood outside his house. Salah didn’t keep them waiting for long though and came out and signed autographs.
