Completely different.
Ronaldo had won it all with Man Utd and had always dreamed of playing for Real.
Lukaku hasn't won anything here and doesn't see the club heading anywhere other than probably another 6th place finish.
Ronaldo was surrounded by Rooney, Scholes, Giggs, Ferdinand, Vidic, Evra and Carrick. All serial winners.
You can't blame Lukaku or any other player wanting out - we aren't progressing off or on the pitch.
Respectfully it's the same. It proves no matter how much money is being pumped in, win pots or not, there is a natural order. If Utd, Bayern, PSG etc. want Lukaku and are willing to pay then nothing will stop him from going.
Where we are in our development is a separate thing altogether, until last year we had two mid-table finishes, we had a midfield of Barry, McCarthy, Lennon and Cleverley. If you can't see progress then sorry to say you're going to struggle to get on in life with those judgement skills.
Is as quick as we want? No, of course not but this is reality and not fantasy land.
