Its bad News for Liverpool. Their star forward Sallah may not play against Barcelona in the second leg after he sustained an injury to the head against Newcastle. This is especially not good for Liverpool who really need to win against Barcelona in the are to go forward in the premier league. 
Klopp said after Sallah was injured:
“He (Salah) got the hip of the goalkeeper on his head.
“He was on the ground, the doctor had to make the decision and that was to take him off. We accepted that, of course.
“He was sitting in the dressing room watching the game, so he was then fine, but, of course, we have to wait because he got a proper knock in that situation.”
