We already have Macca, Gnabry, Gardner and Morrison who can play there, why do we need another RW in Phillips when we could be spending it on an attacking midfielder or full backs? We need other positions strengthening before overloading with right wingers.
Gardner and Morrison should not play there, and just because they 'can', it doesn't mean they should. Morrison hasn't really played there in years, and when he did he was poor - like Gardner he does better centrally.
This then leaves us with McManaman and Gnabry for now.
Well, I think McManaman is too injury prone to be a massive regular, and as good as Gnabry may be, he is only on loan. Thus, it means at least for the future that Phillips would be a good deal.
