Liverpool boss Jurgen Klopp admits Calvin Ramsay is currently injured at the start of preseason.

Klopp described it as a "little injury" but said it could become a long-term issue if they do not "take care of it now".

Klopp said: "Unfortunately, Calvin is now not training with us in the moment, he has a little injury. Nobody knew, we found it when he did his medical check.

"Until today he has no problems but the medical department tells us if we don't take care for that now, he will have a problem in the future.

"So, when you are that young then of course he has a long career ahead of him, so we are very responsible in these moments, so he didn't train yet with the team but is doing a lot of fitness work. So, it will not take too long I think."
