although Lukaku did quite well at Inter, he didn't stand out. last season he played 25 times in Serie A and made 10 goals and assists. after the loan contract is finished, it will be up to Chelsea. but the strongest news is that Inter wants to keep it by negotiating. As for the news from Milan, it has been denied by every agent. as well as news from the Saudi club, because Lukaku still wants a career in Europe.
Lukaku doesn't always start so his performances don't really stand out but once in a while it's very lucky because several times with goals from that as the winner.
I don't know about the rumors about Lukaku but after returning to Chelsea Lukaku was on the sale list to the Saudi League and indeed Lukaku refused even though the offer was very high, in fact he still wants a career among other European teams, but I think the Chelsea coach now it looks like Lukaku will not be included in his new squad.
