Salah age factor which continues to age will certainly affect his performance on the field so that in the future Liverpool will no longer be able to have full hopes for Salah, apart from that, it is reported that Salah is also starting to be targeted by other teams, especially Arab clubs who even dare to pay a lot of money for Salah, and I has even read ,If Salah had received a fantastic offer from Al Ittihad in the transfer market last summer, amounting to 150 million pounds and at that time Liverpool refused to let Salah go, at his current age it would of course be very difficult for Salah to continue to show consistent and stable performance as liverpool expected, like you say that like it or not Liverpool must immediately look for a replacement for Salah at this time, and reportedly there are many names that are predicted to be Salah replacement at Liverpool and one of them is Pedro Neto from Wolves, but so far Liverpool have not shown certainty about recruiting Neto because of the price asked by Wolves very high.
Yes, it is true that Mohamed Salah is a little older, but the problem of getting injured too often is not a problem with his age, but in my opinion, he is still physically strong enough, it's just that he has to rest more often when he has matches scheduled in other competitions so that he doesn't get too tired and get injured naturally, there won't be a recurrence because he has been competing since the start of the full season so it's natural that now he sits on the bench more often to maintain his physical condition and I really hope that in the final match, Mohamed Salah can appear along with the other players.
Regarding the transfer of Mohamed Salah, I think I doubt Liverpool will let go of this player unless Liverpool's coach is no longer Klopp and of course the new coach who will be recruited will greatly influence Salah future, whether he will be sold or retained.
When Liverpool gets a replacement for Klopp with a reliable coach, I'm sure Salah will definitely prefer to stay at Liverpool even though the Saudi Arabian club made a very big offer.
