Liverpool manager Jurgen Klopp on Friday confirmed that Alex Oxlade-Chamberlain will miss the remaining of the club's pre-season programme after sustaining a knock to his knee during training.

"Really unfortunate. An unfortunate situation as well; it was a challenge [in training]. It looks like it is very similar to what Hendo 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 for sure not and then we will see. The next game is probably two weeks later, but I don't know," the club's official website quoted Klopp as saying.
