Inter will still not be in much loss from Lukaku deals so far in case they sign him back for 45 million euros. I mean they bought him for 74 million from Manchester United and sold him for 113 million to Chelsea. There is a decent profit of 39 million euros here. Let's say they signed him back for 45 million their loss will be only 6 million.
The reason why I'm making these calculations here is to show the difference between Chelsea and Inter clearly about Lukaku. Chelsea are in a huge loss considering the amount they signed him back from Inter. Selling him for around 45 million won't change anything.
This is one of the worst journeys for Chelsea about negotiations for a player.
I think inter milan will have to act fast to get Lukaku in this transfer window. Because in some rumors where other teams could take advantage of inter Milan financial difficulties to make a higher bid for Chelsea. Inter Milan front three will be more aggressive next season if Inter Milan manages to recruit Lukaku in this transfer market.
