They're not right wingers, they're attacking midfielders that happen to play on the right. More like Eriksen than, say, Salah.
And I didn't say a creative CM. I said a forward-thinking CM. Conte doesn't seem to like purely creative players, but he does repeatedly refer to wanting players who make runs into the box and arrive late to get on the end of cutbacks and headers - he publicly wanted Hojbjerg to do more of that last season.
McKennie does that a lot, and probably fits the 'Conte' mold more than a pure No.10 type. An interesting option in January could also be Piotr Zielinski - will have 1.5 years left on his contract in Jan, and was angling for a big PL move in the summer.
