Klopp was pleased with Alisson's quick comeback, apparently Alisson is an indispensable part of Liverpool.
Klopp said: "Adrian did a good job, but Alisson's return is an improvement for all of us. He has been absent for three weeks, but I think he has missed 15 games!"
"When he said he was ready to come back, I was really happy. It was his own decision. I couldn't make this decision for him. He felt that he had no pain when he bounced and went down, so he decided to come back early. "
Earlier, Alisson was expected to miss six weeks due to a shoulder injury, but after only three rounds, he returned to the line.
