Definitely, I'd suggest having at least two of them. Any of the them

Saliba - Clean sheets, can score, doesn't get booked easily like Gabriel, always a potential candidate for bonus points

Gabriel - more likely to score than Saliba, clean sheet, can get booked easily

White - Can score and assist, clean sheet,

Arteta would most likely start the season with Zinchenko, but I don't think I'd want to take him on

Thanks for your suggestion.
