If you didn't know their names? Perfectly plausible.
Big English/Irish lads may be visually quite similar, apart from the ginger hair of course.
I wonder if that's why commentators take the trouble to learn the names, as most fans do, rather than rely on clumsy (and possibly inappropriate) descriptions.
Imagine how it could play out in a tussle between Salah and Son....the mind boggles.
