In the end Lukaku was one of the players who made Chelsea lose 2 times in terms of transfers so they also didn't want to let him go that quickly which made them take the option of a loan to get his form back but this did not go well.
Lukaku and Juventus are still linked now and this is what makes Inter look for other alternatives (now Morata) to be their next target.
The problem in this case is that if Lukaku decides to go to a rival this will obviously spark new drama for Inter and Juventus and I expect this to happen because with transfers like this it will increase the intensity and tension in the end.
Lukaku was a bad investment for Chelsea but he is not responsible for Chelsea failure throughout last season, we know what Chelsea did and what affected them in the last concluded season because I can say that loaning Lukaku to Inter was a very good decisions for them with only $8M even when they couldn't win the Champions League, they made it far after a while of zigzag journey and not only that, they finished last season among the top teams in Seria A while Chelsea suffer in Premier League with all the goody players they had on the pipeline.
I don't know why Lukaku transfer is causing many speculations as if it was one of the best expect, I saw Mendy move to Ligue 1 team today and doesn't make reactions that much, I was just happy he is back on track on another journey after a wasteful years but it has always been this Lukaku this and that that without anything to show for Chelsea, he should go wherever he wants in peace.
I'm not saying Chelsea messed up last season because of Lukaku but the point I'm making is that Chelsea lost out by bringing in Lukaku twice at a high price and that's an unavoidable fact.
This is not a question of Chelsea's performance but indeed when Lukaku was at Chelsea he failed to make a real contribution. The 2 times he was there after a brilliant season at the previous club did not bring him to be more successful at Chelsea and it will be very bad if indeed Chelsea still hopes that they realize that the only good thing for Lukaku is to let go of this player.
