That's alright if you think that. If he transforms his game and outgrows his profile, I'll have no issue admitting I was wrong. Players don't outgrow their profiles, though, like ever.
Many players that play in great teams tend to get overestimated to the point where clearly better players that play in lesser teams get dismissed when making a comparison between them. You shouldn't ever underestimate how important the system and environment is to any player. It's by far the most influential thing when it comes to a player being able to perform to their best levels.
I don't see him scoring bucket loads of goals in a team that doesn't dominate every game like City. Their forwards generally get many scoring opportunities every game by just running into big, empty spaces and receive said scoring opportunities with more time on the ball than you would expect. Sure, his hard working mentality, good high pressing, and good ball striking will net him goals and Simeone loves someone who gives his all, even if they're not top drawer, just good...which is what I've been arguing about in this thread.
We talked before about this before...(BOLD PART)
and in general I still think that the jury it's out there of how Julian is going to:
1. Deal with the Aleti style and his current not best level (plus not being a player of the calibre of an Aguero or Tevez as an example).
And I'm not talking here about Aleti in bad form not providing, on contrair even if the team provides him in the best possible way for his style: when he makes his runs in a vertical way into space, this version of Julian might find himself in trouble. Currently he is missing relativily easy chances (specially in the NT).
It's not that he receives the ball many times in such situations (that's also a problem because nowadays I don't think he even knows what role he is playing in the NT and in City), but the ones he has received, he doesn't look as sahrp as he was in his best periods.
2. Deal with the Price tag, for me is perfectly adequate to his talent, CV, current market and the Club is selling. Yet still is a number that the Press will remind him time and again if goals doesn't come and might look awful if he doesn't deliver.
Yet I dunno why on hell man you continue to picture an scenario that wasn't even NEAR as the one Julian had in City, Julian had to scrap the bottom of the barrell time and again in City to receive proper balls and score, to the point that in his last months in there he even looked tired and without confidence when those arrived.
He almost never was the main receiver, when he was alone he mostly also played a role in the middle or the flanks and even when City had him with the main squad, the ammount of times him (and even Erling) ran into space expecting to receive a fast ball where waaaayyyy more than the ones they actually received those.
I trully don't get why you think that City it's a team that constantly had put Julian in scoring postions, it's not. In fact it can be made a 4 hours vid of Walker, Doku, Mahrez, Grealish, Bernardo, sobbing the ball, trying themselves or passing it to Erling (or not even that) than Julian receiving the ball in proper time.
Only Foden in ocassions, Erling a lot and Kevin (in few ocassions that he didn't choose Erling), the ones risking it providing the type of plays you think he was receiving constantly in his time in City. Plus he needs to receive those balls in his rans to space constatly, becasue that it's his best asset, if not he'll ends like Erling surrounded by his rivals and his own team in a tiny area and he is not Foden, no Kun.
So mostly Julian's scenario was playing second fiddle, playing the pressing game, going to the flanks to provide more space for Erling, adding a another body in the middle and offering himself time and agin with runs, but mostly used as decoy. Indeed he isn't a player that can solve by himself in a manner a Kun or Tevez did for City time and again, neither the character to ask for the ball even in a bad manner if they ignore him constantly (that happened a lot), but he also deserved way more balls than the ones he received in his time there.
So finally, there are other reasons why Julian might fail in Aleti, that you've mentioned, that I've mentioned, there are atributes that Julian never had nor will have, but being in the receiving end of easy chances to score constantly wasn't AT ALL his case in City and teh reason behind his numbers or that he played mostly good to very good for them, trust me.
