Alisson Becker has been ruled of Wednesday's UEFA Super Cup final against Chelsea as Liverpool wait to discover the extent of the goalkeeper's injury.
The Brazilian pulled up with a calf problem while taking a goal kick shortly before half-time of the Reds' 4-1 win at home to Norwich City on Friday in their Premier League opener.
He was replaced by Adrian, who only arrived at the club on Monday on a free transfer after Simon Mignolet joined Club Brugge.

And the new boy will now start against Chelsea in Istanbul on Wednesday with Liverpool hoping Alisson doesn't face a lengthy spell on the sidelines.
“With Alisson it is not good but we will find a solution and move on,” said Klopp.
“He felt his calf. He looked behind him because he thought something hit him.
“But Adrian is a good goalie. In possession he is calm and he is good at shot-stopping, that's why we signed him. It's good for him but we have a little problem with Ali."
