Liverpool manager Jurgen Klopp admits having adequate backups is so important in the Premier League.
The Reds have been rocked by news that Andy Robertson is out for three months.
The left-back will have to sit on the sidelines for months due to a shoulder injury he sustained on Scotland duty.
Asked about his backup Kostas Tsimikas being ready to play, Klopp told reporters: “Yeah, very. Very important, that's clear. It always was like this.
“Thank God it's not only Kostas we have for that because otherwise with the amount of games we have we would already be again a bit short.
“But we have Joe Gomez who can play the position, we have Luke Chambers and other young boys who show up in training quite frequently. We had them now in the international break training week until yesterday when the other boys were not in yet.
“You see the young kids really showing up and that's good, there's a lot of talent in there. You need options, that's clear, and Kosti is definitely the most experienced on the position, so that's good.
“But he cannot play all the games from now on so we need other options as well, and that's what we have to make sure: that we can use all of them."
