With the front three being covered and Robbo still being without proper backup, I really think Klopp should consider using Shaqiri as a left back backup.
When he came to professional football left back was his first position he played (at Basel), he later changed to a winger before he got to Bayern. Kinda what happened to Gareth Bale on a smaller scale. So I think it might be worth a shot, what do you think?
