Honestly, I believe it's just speculation, not a true story.
Realistically, both Real and Barcelona are in a major crisis at the moment (specially Barcelona) and can't offer what he already has in Liverpool.
Because of the coronavirus, there is much less money available in football so big transfers are no more realistic as before.
Speculation has a way of making things real later on. I know Liverpool and Klopp will do all they can to keep Salah but as we saw with the Sterling drama and then Coutinho, they know if the player wants to leave, they will not stop them. I think most of this is just noise,,, Salah is always in the news for politics but he knows he cannot find love outside of Liverpool.
Rumors of Salah being unhappy at Liverpool are being talked about more and more, in my opinion Salah will move to Real Madrid. Because almost
everyone knows Barcelona is in a situation of financial crisis right now, the result of Barcelona's very bad management when led by Bartomeu.
So it is very unlikely that Barcelona will be able to bring in Salah, means that Real Madrid is the only strong candidate to bring in Salah.
