Nothing about my post is not factual. Its not an excuse to lay out the fact as they are. The last thing Im ever going to defend is not bandwagoning on platitudes. I even state that he could be in the conversation in the future, but 22 league games in is not the appropriate time to conclude that he is a contender. Marcus Rashford had a better output at the same age in a stronger league. That is factual.
No one is taking anything away from his Champions League performances. Its also worth nothing that the CL is full of one season wonders that never reached that same peak after the first year. Milos Krasic is one player who had a phenomenal CL campaign, only to never get anywhere near that level again. He has 2 goals in the CL campaign, one in a 6-1 thrashing against Ajax, the second on a penalty against Ajax in the return leg.
You can aknowledge that the player is a great talent, without having to go full Ballon Dor contender after seeing a player for 22 matchdays.
My point about the player stands. He is having a breakout season. We can look in house for a player with a better breakout season in Marcus Rashford and ask the same question.
Would he absolutely succeed in the Premier League? Stevan Jovetic, Juan Sebastian Veron, Andriy Shevchenko and Juan Cuadrado are just a handful of Serie A starlets that struggled enormously in a differen/stronger league.
Would he be able to have the same impact on a team that is less dominant? In Serie A you tend to get a lot of time on the ball. Can he adapt to agame where that is not the case? He could, but we dont know that yet.
As much as I love Rashford (and the WC form he is in right now), he's never produced the numbers that Kvicha is producing this season in the league. Yes he's played in a tougher league, but the numbers is not as good, even in his peak season (19/20) where he also had 6 penalty goals.
Here's the numbers:
Rashford (19/20 season age 21/22 - if you can call his 5th season here a breakout season) in the PL:
17 goals (6 pens) and 9 assists in 31 matches (2655 minutes) (transfermarkt assists - includes penalties awarded)
0,58 G/90 - 0,37 npG/90 - 0,31 A/90
Goal contribution per 90: 0,89 G+A/90
Non penalty goal contribution per 90: 0,67 npG+A/90
Non penalty goalthreat (npG+xA/90)
0,55 npG+xA/90 (0,37npG/90 + 0,18xA/90)
Khvicha tihs season in Serie A (age 21 so far):
9 goals (1 pen) and 11 assists in 18 matches (1328 minutes) (transfermarkt assists - includes penalties awarded)
0,61 G/90 - 0,54 npG/90 - 0,75 A/90
Goal contribution per 90: 1,36 G+A/90
Non penalty goal contribution per 90: 1,29 npG+A/90
Non penalty goalthreat (npG+xA/90)
0,95 npG+xA/90 (0,54npG/90 + 0,41xA/90)
Some other context:
Napoli has won 2 Scudettos (Serie A), and both of those were with Maradona more than 30 years ago. They had a good season last season, where they overperformed and many thought they would struggle with key players like Mertens and Insigne leaving. Then they buy this 21 year old from the Georgian League and now they are cruising the CL and is on course to crush Serie A with 100+ points. That's obviously not entirely down to Khvicha, but he has definitely been a major key to their success this season.
Napoli last season vs this season:
Goals per game: 1,94 vs. 2,45
Expected goals per game: 1,67 vs. 2,13
Goals conceded per game: 0,82 vs. 0,68
Expected goals conceded per game: 0,91 vs. 0,84
Points won per game: 2,08 vs. 2,68
Expected points won per game: 1,90 vs. 2,19
They are so much better this season with him and Kim being the biggest variables from last season.
You are right that there is no guarantee that a player doing well one place would do just as well another place, and talk about possible B d'ors is way too early. Impossible to know if he can replicate this level or get even better in the seasons to come, but he has been absolutely fantastic this season. It's allowed to appreciate young "unproven" talents and enjoy their rides up among the stars. I jumped on the Haaland train when he was 17 at Molde, you just knew he was a special kid when you watched him play. Not that sure on Khvicha, but he looks extremely exciting.
Bringing up examples of players not making the cut in the PL is a lazy argument, because you can easily make the opposite argument bringing up players who's made the same switch with success.
