Sacrificing De Ligt for SMS would be similar to Pogba-Higuain deal.
Won't be worth it in the long run and I don't think SMS is a world beater either even though I'd love him here.
as for letting de ligt go, i'm not a fan of the idea, but it's like trying to keep pogba back in the days. if he wants to leave, he will. and honestly, he's the most expensive player of the league, while inda have 3 defenders at his level, at a much lower yearly cost.
genuine question, could you name some world beater midfielders? i couldn't name a lot that i'd sign over sms. de bruyne, pedri certainly, barella, rodri, gavi maybe. and that's all.

sergej is easily a top10 midfielder in my book. if he's available we should certainly sign him.

Okay for some reason I thought SMS was 28. Okay but still I am not sure swapping De Ligt for him is the best idea given that Lotito would demand crazy sums. And I don't think he'll sell him to us either.
oh yeah, i agree with the lotito part. that's what i've been saying for years, he'd rather shoot sergej than sell to agnelli. any sms talk is purely theoretical.
