So far this season it has been very clear that Salah gets lots of help down the right from one of the CMs. Initially this was Elliot, Saturday it was Hendo. Mane doesn't get a lot of this, often Jota is moving into that space a bit, along with the LB but that then takes an option out of the middle. Would be interesting to see how he does if a CM spent more time on an overload. However - maybe this is a good decision as it means Salah / Trent are better able to whip a ball in and Mane is great in the air.
