Bro. I ain't going to argue about Insigne. Stats are a funny thing but it's also good to think about stats in context. Looking at stats in 15/16 where his co-person scored serie A record is NOT context. It is more useful to see what he usually does. Regardless.
Speed
With the ball, his acceleration is average and top speed is below. You can hardly show me him beating players and leaving them for dead. Please do. He either beats them with some skill, but then they recover only a few seconds later (most annoying thing). Or he is cutting inside to create a little space to shoot or pass; but doesn't beat the defender. Almost all the times he "beats" a defender is through a one-two, hardly ever through skill + speed. And in the very few times he is beating somebody, it's on the counter where the defender had to commit; and even in those circumstances, the defender still recovers less than a couple seconds later, then you see insigne cutting back and making a back pass or an inside pass to a midfielder.
Inefficiency (shooting)
I don't have the stats, but I guarantee his shot-to-goal ratio is ridiculous for season 15/16. Probably as bad as a CM (10-11 to 1), whereas good forwards are probably around 5 to 1 or less. And I bet most of those shots come from outside the box. And I bet that if we analyze the shots, it's pretty much like i described above; he cuts inside, gets a little space and shoots a contested shot because he can't really beat people.
Inefficiency (passing)
Like I said, he is always attempting bullshit flicks, backheels, through passes, and long balls. ALWAYS. Again, I will check stats tomorrow, but I guarantee his long passing stats are horrendous. Probably 50% accurate with long passes since he is always trying bullshit. Don't let the short pass stats fool you either. Lots of back passes and passes to midfield in Sarri's system. And please, the "key pass" stat to me is bogus, subjective, and means very little (iniesta's key passes??), but even if you want to use that, I'm sure the ratio of key passes to total passes is ridiculous; probably 1 every 25-30 passes. Probably worst with long "key" passes.
Strength
There's no stat for this and this is just the eye test. Not sure how these stat people count dribbles and say what a dribble is, when it starts, when it ends e.t.c. But by the eye test, he is very weak physically. Easily bodied off the ball.
I get people get dazzled by his what, 10-12 goals and 10-12 assists, but I'm sure they were his highest ever (by a longshot) mostly because Higuain was putting away 1/4 chances, 1/2 chances, everything that came his way. I'm sure his normal goals are probably around 5/6 and assist probably the same.
So no. I personally would not want Insigne. Too weak, too slow, and too inefficient on offense. FYI, I'm not saying he is a shit player. He does have above average skill and he is an intelligent player.
