Ahahahahaha... 😂
Well, looking critically, for Vlahovic, Arsenal is a very good choice for him currently, considering the options of teams where he'd get a starting shirt or those in search of a striker, Arsenal is very much on top of that list. Lacazette wouldn't mind playing behind him.

Moreso, Fiorentina isn't a bigger club even in this current dispensation than Arsenal and the Gunners look to have more prospects going forward with what they're building. Can't say same of Fiorentina, no disrespect.
