Mohamed Salah and Roberto Firmino will miss the second leg of Liverpool's tie against Barcelona in the Champions League semifinals.

Salah suffered a concussion in Liverpool's match on Saturday against Newcastle.

Liverpool trail Barcelona 3-0 on aggregate.

“It’s a concussion so it’s a case of him not even being allowed to play,” Klopp said of Salah. “He’s not allowed to play. He feels OK but it’s not good enough from a medical point of view.

“There’s hope and that’s football,” he added. “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.”
