Liverpool manager Jurgen Klopp has confirmed that defender Dejan Lovren sustained a hamstring injury during their 2-1 defeat at Wolves on Monday night.
Lovren was replaced by 16-year-old Ki-Jana Hoever after just six minutes into the game at the Molineux.
In his post-match press conference, Klopp confirmed the injury and gave an update on his condition.
“[It is his] hamstring, is what I heard – without any signs before. I asked everybody, no signs, nothing, just out of the blue, so that’s the decision you have to make,” he told the club’s website.
“I am not sure what you all would have said if immediately from the beginning if our centre-half situation was Fabinho and Ki-Jana; then probably a few very smart people would tell me that I don’t respect the competition or whatever.
“So, we tried to do all the things [we could]. Of course, on the other hand, it doesn’t make sense to bring in a 16-year-old boy from the start.
“You don’t bring him, you wait until he is completely ready, but he did well. He came on and did well.
“That’s how it sometimes starts – when you are really needed then it is only about if you are good enough and not how old you are.
“He did well, so that was all OK. That’s it.”
Asked when the defender might return, Klopp answered: “I don’t know in this moment.”
