It is rumored that Inter will still bring Lukaku, who is currently back at Chelsea, but the costs might be burdensome for Inter because reportedly Chelsea have also received an offer from a Saudi club to sign Lukaku. As you said, even though Lukaku is a veteran, but yeah his ability is still worthy of being in Serie A, also playing for Inter is what this guy wants. By the way, now Inter Milan already has another striker, Marcus Thuram who is obtained for free, Inter Milan is really deepening the strength of their squad and I'm happy to see it.
Lol Inter is very fortunate to get Marcus Thuram for free despite the market value of €32 million I am not surprised if Inter contract him for 5 seasons with a salary of 6.5 million per season, besides being able to be relied upon Inter will think about other benefits
what Inter need to do is provide opportunities for Marcus Thuram to be an investment in the future, as a young player he still has a chance. I think the decision to bring in Marcus Thuram is an option if Inter fail to bring Lukaku back because indeed the agreement to get Lukaku has been away IMO.
