Now I think that Inter are much stronger with the Lukaku transfer. Even if it is a loan deal I see it as good for them. Because I remember the season Conte's Inter had and won the Serie A title. In that season Lukaku and Martinez both showed incredible performances. They were a superb duo I mean. Therefore I'm expecting to see the same thing again. Maybe Lukaku didn't have a proper season with Chelsea but he seems contented with returning to Inter now. We can watch another great season for him.
With this Lukaku transfer, it will clearly have a much bigger impact on Inter's attacking line and indeed their potential to win the Scudetto is now even greater, especially if you look at their current rivals, namely Milan or indeed Juventus, their readiness is quite lacking, especially Milan also has problems with finances. them so this wouldn't be too good for them.
Hopefully for next season there will be something interesting because if you look at this season, even though it is actually competitive, it feels quite competitive, but some big teams are very doubtful about their consistency.
