Yes, if these two players leave Liverpool at the same time, it will certainly cause a major disruption to the club’s offensive system, despite the presence of Firmino and Diaz, so the Liverpool club must preserve Salah and not allow him to move to another club by negotiating with him about the costs he needs, perhaps Liverpool club management will succeed in persuading him, this is what we hope.
The story is different between Mohammed Salah and Mbappe, if Salah stays at Liverpool then it is a good decision because he is the one who dedicated all the skills he has for Liverpool. As for Mbappe at PSG, he should leave and pursue a career at another club as a long-term foundation. Indeed, Liverpool must be able to carry out quite long negotiations and hold Salah to survive. Even though there are Firmino and Diaz, Liverpool's void without Salah cannot be covered by both.
I think for now Salah will still be at the Reds if he sees his statement some time ago but maybe this is still a fifty-fifty considering in this case of course we can't doubt the power of money and Mbappe is a real example of the power of money alone. It's not impossible that Salah will change clubs when bigger money comes
