His exit prompted an unexpected early debut for Adrian, who only joined the club on a free transfer four days prior, and the 32-year-old enjoyed a quiet evening despite conceding to Teemu Pukki.
Speaking at to Sky Sports after the game, Klopp cast a frustrated view on his No. 1’s injury hopes.
“The Ali situation is a shadow on the game,” he explained.
“He thought something hit him on the calf, that’s never a good sign. Sportsmen know what I mean when I say that!
“That means it’s probably more than a strain. We have to see, make a diagnosis in the morning, but it doesn’t look good.
“Adrian, we brought him in for situations like that. He’s experienced, he’s calm, really good in possession.
“We have a little problem: No. 3. Caoimhin Kelleher is coming back but not 100 percent fit yet. So we have to think again.”
It remains to be seen how long the No. 1 will spend on the sidelines, but the outlook is not wholly positive.
“It’s the calf and that’s it. He couldn’t carry on, that’s not a good sign. We have to see,” Klopp added in his post-match press conference.
“Wednesday, he will not play—with all my experience, I can say that already.”
And as he noted, there will now be a concern over his substitute goalkeeper.
With Kelleher working his way back along with Vitezslav Jaros, it is likely that one or more of Dan Atherton, Shamal George and Ben Winterbottom will make the trip to Turkey.
He revealed, however, that 16-year-old Jakub Ojrzynski is “not even allowed to play,” ruling out one potential deputy.
