its not about the amount...its the type...sterling in particular misses chances that i would say mahrez is more likely to score...for instant one on ones and shots from distance,
you are being picky cause i think i explained that later in a second post so just to put your mind at rest, i wasn't being critical of sterling or Sane (who again, for the third time, i believe will become a better player than mahrez in the future) but that at present he is at least equal to them both and offers something that they don't.
I don't use stats, i use my eyes and maybe you should to instead of being over reliant on simply stats.
