But it is interesting now to see what steps Chelsea will take after overhauling a lot of players who were just released. with the fresh funds they have from the sale actually Vlahovic is also still possible to bring in but as you said, there are several other options about this although it is likely that Vlahovic is one of the players prioritized.
Besides, some news about the exchange of Vlahovic and Lukaku is also still quite busy at this time so this can also be used as one of the good and mutually beneficial options for them
By selling some players to Saudi clubs and got big money from them, Chelsea have good transfer budget and no longer have to worry about financial observation and investigation from UEFA against their club finance. It might come back in future but in this summer, they are good and can enjoy this transfer season to rebuild their team.
Between Lukaku and Vlahovic, Vlahovic is younger and can be useful for Chelsea so it is good for them if they can complete the deal with Juventus. I still don't think Juventus will be ready to lose Vlahovic because they know that striker is younger and has a longer career than Lukaku.
Chelsea has the opportunity to generate income by offloading players, as they possess talented individuals who may not be performing at their best for the club. These players, although not currently shining for Chelsea, have the potential to excel in other teams. Hence, by transferring them to other clubs, Chelsea can acquire new players. However, the catch is that they must part ways with these individuals.
Getting Vlahović instead of Lukaku seems like the wiser choice. Lukaku, the drama-seeking player, is unwanted by clubs due to his dramatic tendencies. Vlahović, on the other hand, offers better value for money.
