The age profile is something to keep an eye though, but unlike Everton, Liverpool can easily absorb the hit of a few 30 year olds.
It really isn't a big deal at all. As said, Salah is only just 26, and Firmino and Mane are not yet 27.
Henderson just 28, VVD just 27, Fabinho not 25 until next month, Alisson not 26 until next month, Wijnaldum isn't 28 until November, Keita isn't 24 until February.
Then we have the likes of AA who is 20 next month, Robertson who is only 24, Gomez is only 21.
