Both caused a disruption in each teams season, adding unnecessary drama and conflict. Both players also had high expectations of them, but both ended their time at the club poorly due to their interviews (yeah Lukaku’s still technically at Chelsea, but he doesn’t really feel like one anymore with him getting loaned out every season).
In my opinion Ronaldo’s interview was totally valid - he’s seen United back in 04 compared to now n was disgusted with the standards etc.
Lukaku just wanted out of a sinking ship tbh kinda scummy etc but I understand why he did especially after the previous season that he had and suddenly he’s back at Chelsea
