Werner easily imo.
Bernardo has had a disappointing season by his standards but I'd still choose him, It's very close though and it could come down to whether you need an attacker or midfielder more.
That's a heavy price to pay but I guess it's worth it for KDB, keeping in mind whoever replaces Son as your winger/attacker isn't too low rated.
Both are good, probably Ikone has a higher ceiling but I see Merino hitting 90 first, although I can see a +1 for them in next review yeah, again depends on what you need more.
Halstenberg deserves it imo yeah..
Havertz by far the bigger talent so him.
Ilicic got one recently so not anytime soon unless football resume and Atalanta pull off another miracle with him being brilliant again.
Gomez it will be hard at this age too, He's a class player but to get a rise now he would need a performace like Illicic which generates a lot of hype, or maybe Atalanta going far in UCL if football resumes, otherwise no.
Zapata, I doubt it because he has been injured for a large part of the season, maybe in the future he can but now.
