The Liverpool goalkeeper starts at St Mary’s after sustaining a freak injury in Istanbul in midweek.
“I’m very pleased about that,” said Klopp. “We tested it this morning. Yesterday it was already better but still swollen. Now it’s good, so obviously not that serious.
“In the first moment it looked horrible when we came out of the plane [on Thursday]. It was really difficult but now he is there and should be fine.”
With Alisson Becker sidelined and Caoimhin Kelleher coming back from an injury, Andy Lonergan is the substitute goalkeeper for the Premier League meeting with Saints.
