We don't have 2 good strikers - never mind 3 or 4 at that position.
Shaq can corver for either of Salah or Mané. Other than that there aren't many wingers available either. Maybe that spot would be something for Moreno?
Shaq is almost as left footed as Salah, so would think he is Salah's cover, though they are both being played. I think we miss one AM which maybe is Lallana. If that's the case then I would like Lallana replaced by a better player in Jan, maybe somebody who could also cover for Firmino.
