Liverpool's Egyptian winger is confirmed to miss Tuesday's anticipated Champions league match against Barcelona due to injury according to coach Jurgen Klopp. “It's a concussion so it's a case of him not even being allowed to play,” Klopp said in the pre-match press conference on Monday. “He feels OK but it's not good enough from a medical point view, that's all,” he added. Liverpool will be hosting the Spanish giants in the return match of the EUFA Champions League semis and Salah's absence will add more woes for the Reds who need a miracle to overturn the 3-0 away loss in the first leg. Salah was stretchered off in the 73rd minute of Saturday's 3-2 league victory over Newcastle after his head clashed with the legs of Newcastle keeper Martin Dubravka. Klopp said after the match that the 26-year-old remained in the dressing room with Liverpool's medics, hinting that the injury was not serious. Before picking the injury, Salah put Liverpool 2-1 up on 28 minutes to take his tally to 22 goals on top of the Premier League scoring chart, two ahead of teammate Sadio Mane and Manchester City striker Sergio Aguero. Liverpool's mission against Barca will be more difficult as key Brazilian striker Roberto Firmino is also out due to a groin injury. “There's hope and that's football,” the coach said. “We are far away from giving up. “Two of the world's best strikers are not available tomorrow – it doesn't make life any easier but while we have 11 players on the pitch we will try,” he concluded.
