I got Immobile in an untradeable pack so I have no skin in the game to talk up his price. All I can say is, he's the best striker I've used in Fifa20. For a direct comparison with a similarly built striker - I had 96 Lewandowski for a while and Immobile is on another level.
I've only played 5 games with him so far but he's scored three in each of them. The reason for sticking this review in so quickly is that Immobile is going cheap given just how good he is. Watch this space, he'll do a Carvajal and increase by 100/150k when people realise just how good he is, so snap him up cheap while you can, anything under 500k is a bargain for this guy.
Heading - I can finally put a cross into the box in Fifa20
Volleys - Bottom Corner every time
Speed - He's a big man in the middle so his acceleration is as important as having the speed to get into the box.
Physical - Unlike some strikers I've played with who have similar stats Immobile stands his ground and rarely gets bullied off the ball.
He's a sword, not a scalpel, there isn't a lot of subtlety to his game - if you're into rainbow flicks and intricate dribbling to score your goals - he might not be for you. If you want a giant pacey forward who bulldozes his way through - this is your guy.
