Andy Robertson will miss out on the Champions League quarter-final against Porto. He has been suspended for this game and Liverpool will need to fill up his place with some other player.
The man most likely to replace the young lad is veteran player James Milner. Milner is versatile enough to play in the midfield, the front three or even in defence.
Milner has previously accomplished the task of playing as a left-back at Liverpool.
Klopp understands the importance of staying in the race for the league title. In order to do that, he needs to be able to field a squad that is competitive despite the injuries that peg the Reds back.
In all likelihood, Milner will play against Porto.
