I think he is being asked to defend more, especially when perisic is playing lwb, so he is deeper when we break, opposition teams are more compact and he has less options to pass to.
We can't expect him to score goals like hi did against Burnley every week, that's not his natural game, but when we transition his starting position is closer to that than where would normally be.
I would consider swapping him and kane, kane helping out on the left and son central and higher.
Son and his pace running onto kanes passing on one side or keeping up with kulu as he breaks in the other.
These aren't bad players, their form isn't what it could be, and it's conte job to get the best out of them, playing the roles they are playing i don't think he is.
I'm sure they know it's not working and i can't help but think that at least some of that is down to not being comfortable in the role.
