It seems very unlikely that Juventus will recruit Lukaku, because I don't think Lukaku has ever asked to play at Juventus. Because anyway, Lukaku seems more suitable to play at Inter because yes, Lukaku also has a strong desire to keep playing at Inter. At least, this was proven when Lukaku played at Chelsea, and then Lukaku stated to be able to return to playing at Inter. With these factors, Inter should be able to bring Lukaku back into the squad, and it looks like it could be the right transfer for the club and also for the player.
I think Chelsea set a selling price too high for Lukaku which in the end was very difficult for Inter to accept. Lukaku is still good, but I don't think his value is higher than 30 million euros, but Chelsea want Inter to pay more. Loan options are being discussed, but it seems Chelsea just want to sell rather than put him on loan again.
Inter have so far not looked like they are going to force Lukaku's transfer at the value asked by Chelsea, that's because Inter seem to want to save a lot of money for other plans. Chelsea had to make a tough decision about Lukaku but I think 30 million euros is a good value for a 30 year old striker.
Lukaku has made a strong contribution at Inter milan and he is very comfortable when playing with Inter milan and I think this will be Chelasa's opportunity to increase the transfer fee for Lukaku so that Inter have to think again whether to take Lukaku because this player is very valuable for Inter milan .
In my opinion Lukaku will still ask to return to Inter milan and Inter will also have a way to continue to be able to borrow and even make Lukaku permanent at Inter milan.
