The Egyptian attacker was unavailable for Liverpool's Champions League semi-final second leg clash against Barcelona, but he watched on from the stands and wore a defiant t-shirt.

Divock Origi kick-started Liverpool's dramatic turnaround at Anfield. He opened the scoring in the seventh minute.
Second-half substitute Gini Wijnaldum, who replaced the injured Andy Robertson, then bagged a quickfire brace.
The Dutch midfielder poked home from close range to make it 2-0, before heading in his side's third.
Origi then made it four from a corner kick. The Belgium forward was brilliantly picked out by Trent Alexander-Arnold who provided a sublime ball.
