Lukaku may join Milan, after Inter almost bought Thuram which was a Milan target for fixing their Attack.
Lukaku was at Inter in Loan, and Milan is aiming to get the same deal from Chealsea.
I don't know why Inter Milan won't buy this player for the next season, Lukaku had a good performance this season. I mean he couldn't prove himself at the start of the season in Inter Milan but recently and especially in the last weeks in the Serie A and Champions League he had a good enough performance and helped his team enough. Ac Milan offered 4m for hiring this player but I think Inter Milan had to buy him because of the season he spend there.
There are several conditions that Inter might look at in the Lukaku case.
Firstly, he has a very high price and of course this will disrupt his financial condition if he is forced to buy Lukaku because we know that Lukaku will not be released at a low price for Chelsea, at least it still allows the price to be above the average player.
Second, the performance is not too bad but it's just that with the high salary and the value that is still high for Lukaku I think it's still lacking and of course this is not a good thing for a player who does have high values but his performance doesn't match the price and salary .
I think in this case Inter are clearly quite good at making decisions because bringing in Lukaku also apart from draining their pockets, their performance is clearly still far below the average for an expensive player.
