Jurgen Klopp says Mohamed Salah could carry on playing until the age of 40 after the forward announced he will leave Liverpool at the end of the season.

Speaking to BBC Sport in Liverpool before an LFC Legends charity game, Klopp said: "Salah is an incredible professional.

Klopp, who left Anfield in 2 ppl024, was the manager who signed Salah for the Reds from Italian side Roma in 2017.

The Egypt winger, 33, has since scored 255 goals for Liverpool, with only Ian Rush and Roger Hunt ahead of him on the club's all-time list.

"He set completely new standards for a professional football player - how hard you can work, how much you can invest in recovery and everything."

The German added: "Now he leaves here but I would not be surprised if he plays another six or seven years.

"I'm sad but he's an all-time great without a shadow of a doubt and I'm really proud to be a part of that career."

"He knows this was the perfect club for him and he was the perfect player for us," said Klopp.

"Mo and I had big dreams, but we didn't dare to dream that big. I'm not sure we can appreciate it to the right extent - that will happen soon now. I wish him the best of luck because he deserves it.

"The numbers he produced and the standards he set, some of them, if not all, will stay unmatched in this modern Premier League era, definitely, because it's ridiculous to do that, and to do it for one club more or less."

Klopp, 58, added Salah is "one of the best" professionals and people he has met.

He said: "We texted the other day and we had our arguments, but it was always for the right reasons. It's always fine, especially now looking back, it's more than fine. And we are both really happy about being part of that incredible journey."

Asked whether it was the right time for Liverpool and Salah to part ways, with the winger still having a year left on his contract, Klopp said it was a "fair deal".

"It's not about me to make that decision but I think it's right that there's an agreement," said the German.

"I really think the whole relationship was a fair deal. An exceptional player, exceptional numbers, and he earned some money, of course.

"And now he can go wherever he wants and the club will have to find and will find other players, and that's absolutely OK.

"After all these years there should be no bad sentiment at all and as far as I'm concerned I can't see any."

Klopp admitted Salah will be "irreplaceable" but urged his former side to "find a new way" to play.

Next season will be the first time since 2016 Liverpool start a campaign without Salah in their squad.

"Yes, this specific kind of player is irreplaceable. That's always how it is. There will be a void that somebody will fill," Klopp said.

"The numbers for a winger are ridiculous. For a striker they are pretty much unmatched. That's how it is. So, if it is impossible, why should you try?

"I'm not in the role to advise anyone. But just bring players in and play the kind of football which can be successful. That is pretty much everything.
