Right from the get-go, the young defender was embroiled in an entertaining feud with Diego Costa, but while the former Chelsea striker attempted to use veteran moves like little shoves off the ball or getting in the referee's ear, Upamecano remained as cool as a cucumber to keep Costa quiet.
Upamecano hasn't arrived yet, he seems like a foreign body.
To have completed 89 percent of his passes this term whilst averaging six long-balls per game is quite some feat.
He is generally happy to get tight to players, and only backs off to hold his position when there is no cover available, or when caught out on the counter-attack.
