I think it all fell apart when Costa didn't respect Conte after knowing that the Chinese club came for him. Remember how he refused to train? well can't blame Conte for that. Conte is the boss he probably doesnt want to deal with the fact that he has a player who refuses to cooperate at the crucial junction in our title race again, nothing wrong about that. Even if we did have Costa I think we need a/another top striker to compete in all competitions.
It would be a stroke of genius if Conte can defend the title this season judging by how our transfer market is going( I know it is a little early but still). There isn't a sense of urgency shown from our club. Really hope that Lukaku wasn't in our radar and it was just a fantasy story cooked by some journalists to get viewership.
