The good feelings is that Lukaku is now in Roman for the rest of the season on loan, he never wanted to leave Inter Milan, he always love the club but they disappointed him and made him look stupid. In football things like this happens but the happiness of footballer matters that's why the Saudi Arabia pro league is Excel now. They give players good comfort.
Not everything has to be compared like that even though it is both football, because the Saudi Arabian professional league is inhabited by teams with a very large financial level so that it clearly makes the players more comfortable to be there. Meanwhile, in Serie A, Inter Milan and AS Roma have very different financial strengths so it is not feasible to compare them with the teams in the Saudi Arabian professional league. After all, Inter Milan also used Lukaku on loan last season and that was not much different from what AS Roma did this season.
Each player has their own ambitions to pursue their career. Lukaku is indeed confused about his future, so he has made several decisions that threaten his own career. I think he still has the desire to play at a high level even though he was willing to have his salary cut when he agreed to wear the Roma uniform. In fact, Lukaku also received an offer from the Saudi Professional League but he didn't budge. So I don't think Lukaku is thinking about happiness with a tempting offer from a Saudi club but he prefers to play in a competitive league like Serie-A, maybe he also sees that opportunity to be called up to the Belgian national team.
