Mahrez has more goals + assist per 90mins in the PL this season than Salah. He’s been fantastic and has been let down by others.
And yet Liverpool have already won the title...at a canter.
As I said, it is not about Mahrez being a bad player, its about the good of the team as a whole. Salah is fine doing what he does because he has TAA behind him, bombing forward creating chances and getting double figures for assists every season. Same for Mane with Robertson behind him. Mahrez has Kyle Walker, standing on the halfway line, passing to Ederson.
If our full backs cant/won't get involved our wingers have to deliver far more. From a G/A per mins ratio, you might be correct (I haven't checked) but Mahrez has 9 league goals, Salah 17. Salah would arguably be disappointed with his return of 17 and yet we celebrate 9 from Mahrez because of the mins per action is better?
For me, we have a couple of options:
Option 1: We buy much better full backs who can produce in the opposition half, allowing Sterling and Mahrez to spend more time infield, where they must deliver 15-20 league goals apiece, as Mane and Salah do for Liverpool.
Option 2: We go back to what worked so well for us before, Sterling on the right and use Mahrez as a squad player.
Option 1 costs significant GBP with no guarantees of success.
Option 2 costs the amount of a new left winger and while it also doesn't offer any guarantees, we have seen it work previously.
