Salah notched 27 goals last campaign and is currently on 18 goals this season and former Italy forward Del Piero has hailed the forward.
"Salah is already a god - and not only in Egypt," he told JOE.
"When he was at Roma, I remember how many times he was in front of the goal and then he missed the goal.
"And then all of a sudden, at Liverpool he improved that and he scored more than 30 goals per season.
"When you have this kind of mentality that you want to improve yourself, to grow - it's the best thing."
