Next season I see that Inter Milan is a strong candidate to win the Scudetto because their squad has seen good perfection this season. Maybe Lukaku will return to play from the start of the season next season because last season he was hit by an injury which prevented him from playing fully in every game. Martinez and Lukaku are the stickers that are very feared in the next season. Dzeko is gone and he has made a big contribution to Inter this season.
Romelu Lukaku's loan contract is about to end by the end of this month. Inter don't seem like they are very interested in extending this contract or signing him permanently. Because Lukaku is far away from his old look now. He is playing really inconsistently and you know how he played a serious role in Inter's not being able to resist Manchester City more by playing extra time.
Therefore his recent performance isn't convincing enough for Inter to fight for him. They were really keen on signing him on a loan deal before because they were hoping to see the same effort from him. As you know they were a great duo with Martinez. But now there is nothing left of it.
Correct, Lukaku loan contract is about to end at the end of June, yes this month. As you said Lukaku last played with Inter is against Manchester City in final UCL and it was very disappointing, and I also think that Inter may not want to extend his contract. Although at the moment there is no official news regarding Inter and Lukaku, but I think Inter have a firm stance, the failures of this season will not be repeated in the next season.
