"He's doing alright," Ferdinand said on 'BT Sport' after comparisons were drawn with Cristiano Ronaldo.
"To put it into perspective, Salah is talked about rightly as having an unbelievable season. But he's going to have to do that for the next 15 seasons to get to that mark.
Former Liverpool player Steven Gerrard echoed these sentiments, claiming Ronaldo and Lionel Messi are still in a class of their own.
"It's not human, those numbers and those statistics. He's operating on a different planet and it's only Lionel Messi who you can really compare him to," Gerrard said.
