Lukaku is a very talented player. And Mourinho knows well how to use a talented player. Mourinho has established a friendly relationship with Lukaku. And Lukaku finds out its weaknesses. And Lukaku has been doing well with Roma this season. He scored 6 goals in 10 matches with Roma. Whereas Lukaku scored just 8 goals in a full season with Chelsea.
It is not certain whether Mourinho will leave Roma. But I think Roma management will not want to lose Mourinho. The team's performance has improved since Mourinho took over as Roma coach. If Roma management changes coach, Roma's performance will once again become weak and erratic.
Since Jose Mourinho's arrival to Roma, this team's performance has improved rapidly so it would be a shame if Roma decided to collaborate with him. The arrival of several star players to the Roma squad was also an effect on Mourinho, such as Lukaku, who has started to find his touch again since wearing the Giallorossi uniform. Mourinho and Lukaku are like two sides of a coin that cannot be separated. So as a Serie A fan, I really enjoyed the moment of Roma's revival with Mourinho and I really hope that Roma management can maintain it for the next few seasons.
To say it's improved a lot I don't think so, although I don't deny that Jose's arrival brought about a lot of good changes for AS Roma. But even so, they also have to improve their performance again, because they are also now still difficult to compete tightly for the race to become champions.
Jose Mourinho knows very well that this club will not be easy to bring up rapidly and immediately become a major competitor in the race for the scudetto. But I also see them still up and down in performance and cannot be consistent. That's what makes them still difficult to penetrate the competition at the top.
