Archer and Watkins would be formidable.
Both for me. I know Ollie looked a bit lost on Saturday, but I still think he can play the Mane / Salah role and score plenty of goals. But If it was one or the other I think Ings would probably be the better link player in a narrow 3 up top.
Trouble is Mr. Gerrard seems to prefer Davis atm. I don't know what it is about him and Villa Managers. Maybe they like the theory of a Davis-type player if not the execution.
