“(It is) really unfortunate. n unfortunate situation as well; it was a challenge (in training)” Klopp told liverpoolfc.com.
“It looks like it is very similar to what Hendo (Jordan Henderson) had, which keeps him out for we don’t know for sure exactly how long.
“But for sure this pre-season he will not make a game – Arsenal (in the Community Shield) for sure not and then we will see. The next game is probably two weeks later, but I don’t know.
“We have to wait but it is far away from being perfect, of course. It is really hard for him and hard for us, but it is not to change.”
