Mount and Gomes also coming thru.
Sessegnon is more of a goal scorer than creator.
You don't need to have someone on the level of a Eriksen, if all of your midfielders/wingers can pass and move and make quick decisions. If Sterling can play decent through balls, then the likes of Sancho, Foden, Gomes, Mount can too, who are all better technically than Sterling is, with the manipulation and passing of the ball. Also with the pace that Sancho, Hudson Odoi, Sessegnon have, they don't need the ball to be perfect.
