As for what actually happened:
First official contact with Chelsea took place around those days.
Bid came a few days later. Inter wanted to sell, Lukaku said no.
Then Chelsea upped their offer to Lukaku and he wanted to go.
We sold him for €115, so please tell me how it's possible to negotiate down from a supposed 130m offer to 115m... Does Coursera explain that in their Good Negotiations topic?
P.S. It was £74m, which corresponds to €80m.
Inter Milan have signed Romelu Lukaku from Manchester United, bringing an end to their pursuit, which has lasted the majority of the summer.

Inter Milan reach an agreement with Manchester United to sign striker Romelu Lukaku for a fee that could rise to £74m.

There was also a small % that goes to Manchester United so we probably paid 84-85m for him after his sale to Chelsea.
Yes, the base fee was 65m but you're fooling yourself if you think we didn't meet most of those silly clauses that took the deal to 80+.
