Liverpool beat Julian Nagelsmann’s RB Leipzig 2-0 but the German boss was not short of complaints.
“At the stage when we played Bayern and Manchester [United], it was the Justin we were hoping for,” Nagelsmann said. “After that, he was gone again.
“He just trains very little, I don’t see him much in training. That’s the problem. He has to become more stable in terms of his body.
“Since he’s been here, he’s had far too few training sessions and therefore too little impact on the game.
“He basically has skills that would have done us good in the game against Liverpool. They would also do us good in the Bundesliga, like his deep runs and fast dribbling. He’s also a goalscorer and has a good finish.
“But he simply has to become more stable. He’s a little too injury-prone these days.”
“Obviously, we hope he has an even bigger impact on a successful season, that he stays healthy and that he can train more and get fit again for the games,” Nagelsmann added.
“He’s welcome to do as well as he did against Bayern Munich.
“In the course of the second half of the season, we will then decide what we do and what he wants to do. And how big his influence was and how it then continues beyond the summer or not, we will decide then.”
