The German goalkeeper headed home on a season-long loan in 2020-21 but saw little game time and now faces another big call
Loris Karius is preparing to make a decision on his Liverpool future, with the German goalkeeper admitting that a loan move to Union Berlin in 2020-21 was a mistake.
The 28-year-old headed home as he remained some way down the pecking order at Anfield and was unlikely to edge his way above the likes of Alisson and Adrian.
Having previously spent time with Besiktas in Turkey, another short-term deal was put in place, but just four appearances were taken in for Union by a man approaching the final 12 months of his contract on Merseyside.
