The Egyptian forward claimed back in December that he would be open to joining La Liga star club Real Madrid and Barcelona.
In an interview with Marca, Salah admitted that it is very possible that he could be on his way out of Anfield in the future.
"I hope to be able to play for many more years," Salah said, who is currently on international duty with the Egyptian national team.
Salah's contract runs until the summer of 2023, and there have been plenty of reports linking him a move either this summer or the next so that Liverpool avoid him going for a cut-price deal.
When asked about possibly moving to Spain, Salah admitted "Why not? No one knows what's going to happen in the future."
"So... maybe one day, yes. It's not up to me," adding "We'll see what happens but I prefer not to talk about that now."
Salah was also asked on his relationship with Liverpool manager Jurgen Klopp, to which Salah responded by saying that "It's a normal relationship between two professionals. That's how I'd describe it."
These responses are similar to the ones he gave back in December during an interview with Spanish outlet AS, when he was asked if he would completely rule out a move to La Liga in the future.
Back in December, he stated "I think Madrid and Barcelona are two top clubs."
"Who knows what will happen in the future, but right now I am focused on winning the Premier League and the Champions League with Liverpool again."
Liverpool will be facing one of the clubs that Salah is linked with, as they play against Real Madrid in the Quarter-Finals of the UEFA Champions League.
