Lukaku's condition is really unfortunate. He is expected to be out for 3-4 months because of avoiding surgery as far as I have heard. That's sad news for especially Conte... He is his number 1 in the squad you know.
Now honestly, I think this situation will force Conte to sign a new striker. What do you think? Lorenzo Lucca shouldn't be a player they should rely on during this time period. They can at least go for a loan move on a sensible CF.
