Batshuyai is a terrible striker. I don't get how you're throwing him around, he's just a poacher you throw in last minutes if you want a goal, basically a downgraded version of Chicharito. Of course Lukaku is better than him, but that doesn't mean much considering the terrible competition, and they need Mertens in other position than the striker one. Lukaku is the only good Belgian striker available so using the national team is stupid.
The only fact is Lukaku has been a bigger flat track bully for Belgium than even for Everton. Almost all his goals for them came against shite oppositions and they play these teams a lot. He still doesn't score much or even look like getting chances to score against any decent oppositions they play. He sure will score a hattrick against Saudi or Gibraltar, doesn't mean much, and Belgium play these awful teams in their friendlies and qualifiers far more than the decent ones.
And you didn't replay my question, which big club is going to take him now ? Maybe you didn't answer because there's literally no one ?
