Irish goalkeeper Caoimhin Kelleher could be in line to make his Premier League debut with Liverpool after Adrian suffered a freak ankle injury during the Super Cup victory over Chelsea.
Reds boss Jurgen Klopp revealed the Spaniard was hurt when a pitch invader landed on his ankle during the post-match celebrations in Istanbul.
With first choice goalkeeper Allison Becker already ruled out until September with a calf injury, Adrian's absence could see Kelleher called up, even though he has just returned to training following a wrist injury.
While Klopp is hopeful Adrian will be fit, he is prepared to call-up Kelleher if he has to.
"Yes. If we have to make a decision, then we make a decision," the Liverpool boss said. "Caiomhin is a boy we are all excited about.
"He's now in training, but not 100 per cent yet. He has to be in training today, then we will see."
It was Adrian's save from Tammy Abraham in a penalty shootout which secured the Super Cup trophy for Liverpool.
Asked whether his shootout heroics would boost his confidence, Klopp responded: "It would help him a lot if it would be 100 per cent clear he can play tomorrow.
"A supporter jumped over something, was chased by some security guys, slipped and kicked his ankle. It's crazy.
"Yesterday it was swollen, today I spoke to him he said 'it's much better than yesterday' but we have to see. Apart from that it was a brilliant night for him, not only because of the penalty but also because of the game."
