I think you are overstating Juventus’ recent fall. Up until the past couple years, they were a lock to win the league, and expected to make a decent CL run. They’re down right now, but I think they still compare favorably to the 4-7 teams in the EPL. for me, if he gets a chance to go somewhere that’s clearly a step up, and willing to give him a shot at starting, he should consider it. But Liverpool, Chelsea, City, Bayern, PSG, Madrid, and maybe Athletico are the only ones I would consider to be a step up. Any others, like Arsenal, Tottenham, or inter, would need to offer a big raise to make a move worthwhile, IMO.
