what we need as a attacking point of view is a pacey player that can take people on and deliver a end product whether that be a cross of a defence slitting pass
I don't know about pacey player, but we have firmino who can deliver defence splitting passes, as can coutinho etc.
ojo fits what you are describing. as long as the player provides width and are good for us off the ball (which entails a lot of things and is 60% of the battle imo) then they don't need bags of exceptional pace although it helps. they do need to be able to do things like run beyond the striker like reus/lamela etc can. I'm sure klopp will switch his attention back to players like sane, he has the bonus of some pace. whoever our new winger/attack midfielder is hopefully make successful dribbles, get themselves into positions to make key passes, be able to track back and make tackles.
