By the way Lukaku is pretty close to reaching an agreement with Inter nowadays. It is most likely to be a loan move for him but he would still take this chance anyway. Because he hasn't been very happy with playing for Chelsea for some time. Chelsea are aiming another thing by this transfer too now. They aim to sign Denzel Dumfries after sending Lukaku. As Chelsea are looking for defenders now this would be really logical for them. Dumfries is one of the qualified defenders now.
Denzel Dumfries is mainly played on right midfielder, even he can played on right back, but he almostly played on right midfielder. I don't think Chelsea want to buy Dumfries is a good move because they already have Reece James who're excellent on the right midfielder. I don't really know what's the purpose of Chelsea now, perhaps they want to try their strategy even though they will need face trial and error.
I agree with Chelsea move to buy center forward player e.g. Richarlison, it's more make sense if Chelsea buy a new goal keeper since Mendy isn't really good.
