Agree. Salah has a big role, Liverpool will decrease their attacking power significantly if Salah is leaving Liverpool. We must remember Liverpool performance is decreasing a lot when Mane left the club. I can't imagine if Salah leaves Liverpool, too. I doubt if Klopp can get a proper player to replace Salah's position. Klopp even failed to get a proper replacement of Mane.
It is true that Salah has a huge role in Liverpool; yet Salah is an old winger and would replaced soon by Liverpool anyways
The best opportunity would be to let go while making good amounts of money fit to get a quality replacement in the mold of Mohammed Salah.
Talking about Salah's replacement I don't think there's any person Liverpool has found at the moment as a better replacement for Salah so till the end of the season he's still going to be in Liverpool except at the expiration of his contract neither him or Liverpool is willing for him to leave he's still going to stay, I still believe he's still got some time at Liverpool.
He age is yet to be a factor that will cause Liverpool to drop him because his performance is still at its peak he isn't showing any signs of age affecting him yet neither has his form drop and he has been a very vital and key player in Liverpool all along even up until he left to defend his country, he was still very vital in all Liverpool games where he featured ,he's still one very good player Liverpool has got and will not be willing to let go so soon except the need for such arises.
Currently, I have never seen a report confirming that Liverpool have actually seen a potential replacement Mohammed Salah when he eventually leaves the club during the summer but considering the numerous young talented footballers that plays in Mohammed Salah's position, I think there's a possibility of finding some who'll perfectly replace the Egyptian when he finally leaves.
Jurgen Klopp is known as one of the most experienced managers of his generation and he's capable of moulding young talents into becoming great footballers just as we've seen in the past. Salah I think will definitely leave in the summer and when he leaves, I'm optimistic that Liverpool will as well get a player who'll perfectly replace him at the club
