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.
Lukaku's form at Chelsea has been very erratic and I think his contribution to the team last season really didn't live up to expectations. Don't know where the fault lies, but that's what I saw from Lukaku last season. The number of goals he has scored is in contrast to what he did with Inter in the previous 2 seasons in a row. Maybe not not suitable to play in the Premier League because of his stature and weight, he is better in Serie A.
The total goals scored by Lukaku during his last season at Chelsea was minimal as he only scored 12 goals in all competitions from a total of 38 appearances. That's half of his goal tally at Inter so maybe this has him thinking about moving on again to Inter next season.
