There were talks about Rodrygo going to Liverpool for after Salah replacement. He is still at Real Madrid this season, that part is guaranteed, and Salah will be at Liverpool for a while longer. But in a year or two, Liverpool could get him, and specially if they can win the title again, they could have money again. They spent 150 million on Wirtz this season, so that should tell you that they have the money specially for Rodrygo, they had one for this year, so it is not impossible.

It may not be for every season, but if they skip next season, then the year after that, they can get Rodrygo, plus he would become cheaper by then if Real Madrid is not using him. And considering Salah would probably be gone in 2 seasons, he would be an amazing replacement without a doubt.
