Echo this. Obviously I'd like to see Pep give Mahrez a Salah-like transformation, but statistically how likely is that to happen? How many Salahs have we really seen? Let's not forget Pep also repeatedly says that if a player doesn't already have a good degree of talent, then Pep can't perform magic.
So it seems to be it's a bit of a game of probability here where we're kind of relying on Mahrez to have some enormous untapped potential at the age of ~28. And, if history is to go by then the odds don't necessarily seem to be stacked in Mahrez' favor to pull a Salah.
On the flip side, I guess if we can't sign a top player, then what more can City do? Gotta get someone and not leave gaps in the squad.
